DeVito was born at Raleigh Fitkin-Paul Morgan Memorial Hospital in Neptune Township, New Jersey, the son of Daniel DeVito Sr., a small business owner, and Julia DeVito (née Moccello). He grew up in a family of five, with his parents and two older sisters. He is of Italo-Albanian descent; his family is originally from San Fele, Basilicata, as well as from the Arbëresh Albanian community of Calabria. He was raised in Asbury Park, New Jersey. He lived a few miles away from the original Jersey Mike's location and would eat there frequently, which would inspire him to become the sub shop's first celebrity spokesman in a line of commercials that began to air in September 2022.

DeVito was raised as a Catholic. When he was 14, he persuaded his father to send him to boarding school to "keep him out of trouble", and graduated from Oratory Preparatory School in Summit, New Jersey, in 1962. While working as a beautician at his sister's salon, his search for a professional makeup instructor led him to the American Academy of Dramatic Arts, where he graduated in 1966. In his early theater days, he performed with the Colonnades Theater Lab at the Eugene O'Neill Theater Center in Waterford, Connecticut. Along with his future wife Rhea Perlman, he appeared in plays produced by the Westbeth Playwrights Feminist Collective.

DeVito started his career acting off-Broadway in the plays Shoot Anything With Hair That Moves and The Man with the Flower in His Mouth both in 1969. DeVito played Martini in the 1975 film One Flew Over the Cuckoo's Nest directed by Milos Forman, reprising his role from the 1971 off-Broadway play of the same title. He had his feature film debut in the drama Dreams of Glass (1970). Early film roles include Lady Liberty (1971), Hurry Up, or I'll Be 30 (1973), and Deadly Hero (1975).

In 1977, DeVito played the role of John "John John the Apple" DeAppoliso in the Starsky & Hutch episode "The Collector". DeVito gained fame in 1978 playing Louie De Palma, the short but domineering dispatcher for the fictional Sunshine Cab Company, on the hit TV show Taxi. For his performance he received a Primetime Emmy Award for Outstanding Supporting Actor in a Comedy Series and Golden Globe Award for Best Supporting Actor – Series, Miniseries or Television Film.

After his breakthrough on the sitcom Taxi, DeVito devoted more effort to a growing successful film career. He took a supporting role as Vernon Dalhart in the James L.

Confidential with Russell Crowe, Guy Pearce, and Kevin Spacey, the latter of which was nominated for the Academy Award for Best Picture. That same year he also voiced Phil in the Walt Disney Animated film Hercules (1997). Leonard Klady of Variety praised the voice performances writing, "As in Aladdin, the melding of character animation with the screen personae of the actors voicing the roles provides forceful and amusing entertainment, particularly in DeVito's turn as a physical trainer and the acid wit James Woods brings to his villainous role."

He starred in Living Out Loud (1988) alongside Helen Hunt and Queen Latifah, reunited with Kevin Spacey in The Big Kahuna (1999), and hosted the last Saturday Night Live episode before the year 2000.

However, he declined to audition for the role, commenting that he was unfamiliar with the franchise.

In April 2012, DeVito made his West End acting debut in a revival of the Neil Simon play The Sunshine Boys as Willie Clark, alongside Richard Griffiths. It previewed at the Savoy Theatre in London from April 27, 2012, opened on May 17, and played a limited 12-week season until July 28.

In 2013, he would voice Herb for a third time in the episode "The Changing of the Guardian". DeVito made his Broadway debut in a Roundabout Theatre Company revival of the Arthur Miller play The Price as Gregory Solomon. He acted opposite Mark Ruffalo, and Tony Shalhoub. Marilyn Stasio of Variety praised DeVito's performance writing, "DeVito, who holds the audience in the palm of his hand, tends to favor the comic side, making an extended meal out of an egg-eating visual gag. But he also draws on down-to-earth Jewish wisdom to keep family hostilities from boiling over and spoiling the financial negotiations". He went on to be nominated for a Tony Award for Best Featured Actor in a Play. The production began preview performances at the American Airlines Theatre on February 16, 2017, and opened on March 16 for a limited run-through on May 7.

In 2018 he had a guest starring role in the Netflix comedy series The Kominsky Method acting opposite Michael Douglas and Alan Arkin. He also voiced Dorgle in the Warner Bros. animated film Smallfoot (2018).

In 2023 he acted in the Disney horror comedy Haunted Mansion, Chris Pine's directorial film debut Poolman, and the Illumination animated film Migration. Also in 2023 he returned to Broadway in the Theresa Rebeck play I Need That.

DeVito made his directorial debut in 1984 with The Ratings Game. In 1986, he directed and starred in the black comedy "The Wedding Ring", a season 2 episode of Steven Spielberg's anthology series Amazing Stories, where his character acquires an engagement ring for his wife (played by DeVito's real-life wife, actress Rhea Perlman). When the ring is slipped on his wife's finger, she is possessed by the ring's former owner, a murderous black widow. In 1987 he made his feature-directing debut with the dark comedy Throw Momma from the Train, in which he starred with Billy Crystal and Anne Ramsey. For his performance he earned a Golden Globe Award for Best Actor – Motion Picture Musical or Comedy nomination.

DeVito reunited with Jewel of the Nile co-stars Michael Douglas and Kathleen Turner in 1989 when he directed and starred alongside them in The War of the Roses. In 1996 he directed Matilda (1996), a film adaptation of Roald Dahl's 1988 classic children's novel of the same name. Critic Roger Ebert of The Chicago Sun-Times wrote, "There is never a moment (except toward the happy ending) that we sense DeVito is anything other than quite serious about this material. He goes with Dahl's macabre vision." He also served as the Narrator and played the villainous used-car dealer father Harry Wormwood opposite his wife Rhea Perlman. The following year, he was in talks to direct the crime drama The Little Things with Robert De Niro at that time set to star, and The Crowded Room with Leonardo DiCaprio. Both projects were eventually realized in the 2020s, but without DeVito's involvement.

In 1998, he committed to star in and direct both the sci-fi film Barthe for TriStar, about an alien who falls in love, and a remake of The Man Who Came to Dinner for DreamWorks. In 1999, DeVito was attached to star, direct and produce Jason Keller's spec script Sugar's Sweet Science of Bruising for New Line Cinema.

For the next two years, DeVito was attached to film Michael Petroni's Revelations, a "supernatural religious thriller" that was to have starred George Clooney. The project was delayed due to rewrites however, and DeVito instead resurfaced with Death to Smoochy (2002) and Duplex (2003), which he made back-to-back. Before the release of the latter, he agreed to direct a remake of 1942's I Married a Witch for Tom Cruise and Columbia Pictures, announcing to Variety that he hoped to begin production by the end of the year.

Instead of I Married a Witch, he sought to make Trump vs. Wynn as his next directorial project after receiving an offer from HBO. Written by Rick Cleveland, the script chronicles business tycoons Donald Trump and Steve Wynn's competition to build a casino in Atlantic City. DeVito was expected to direct, produce, and star in an unspecified role, but he dropped out after meeting with both figures, who protested the film's production.

He directed the pilot episode for a proposed 2005 Imagine TV sitcom Queen B, which was not picked up by the network for series.

In 2009, it was reported that DeVito would direct and produce the biopic Crazy Eddie, based on the life of consumer electronics king Eddie Antar, from a script by Peter Steinfeld. However the film could not be made due to a life rights deal that was made with Antar. Instead, he pivoted to making the apocalyptic horror thriller St. Sebastian, which completed post-production in 2012 but to this day has not been released. DeVito also worked on the independently financed Honeymoon with Dad, a comedy which never went into production.

DeVito has written a film adaptation of, and been, since 2008, attached to direct The True Confessions of Charlotte Doyle with Morgan Freeman, Pierce Brosnan and Saoirse Ronan starring. The production was halted when Freeman was seriously injured in a car accident two weeks before filming was scheduled to commence. DeVito returned to the subject in February 2013, saying he was looking for another young actress to star in the title role and scouting movie locations in Ireland. Production was expected to restart in July 2014. The release date is still classified as "TBD" without any new information as to whether it will be shot.

DeVito founded Jersey Films in 1991, producing films like Pulp Fiction (1994), Get Shorty (1995), Erin Brockovich (2000) (for which he received an Academy Award nomination for Best Picture), Gattaca (1997), and Garden State (2004).

DeVito also produced the Comedy Central series Reno 911!, the film spin-off Reno 911!: Miami, and the revival on Quibi.

In 2019, his company Jersey Films optioned the screen rights to make a film of Toms River: A Story of Science and Salvation, by Dan Fagin.

DeVito stands 4 feet 10 inches (1.47 metres) tall. His short stature is the result of multiple epiphyseal dysplasia (Fairbank's disease), a rare genetic disorder that affects bone growth.

On January 17, 1971, DeVito met Rhea Perlman when she went to see a friend in the single performance of the play The Shrinking Bride, which featured DeVito. They moved in together two weeks later and married on January 28, 1982. They have three children: Lucy Chet DeVito (born March 11, 1983), Grace Fan DeVito (born March 1985), and Jacob Daniel DeVito (born October 1987).

Perlman and DeVito have acted alongside each other several times, including in the television show Taxi and the feature film Matilda (where they played Matilda's parents). They separated in October 2012, after 30 years of marriage and over 40 years together, then reconciled in March 2013. They separated for a second time in March 2017, but remained on amicable terms and Perlman stated they had no intent of filing for divorce. In 2019, Perlman told interviewer Andy Cohen that she and DeVito have become closer friends after their separation than they were in their final years as a couple.

DeVito and Perlman resided in a 14,579-square-foot (1,354 m) house in Beverly Hills, California, that they purchased in 1994, until selling it for US$24 million in April 2015. They also own a bungalow near Rodeo Drive in Beverly Hills, and a multi-residence compound on Broad Beach in Malibu. They also frequented a home they owned in Interlaken, New Jersey, to get away from Los Angeles.

DeVito has mentioned being a big fan of singer Mike Patton's various musical projects, being introduced to his work though his son Jacob in 2005. DeVito collaborated with Patton on a music video and has attended several of his concerts, with Perlman contributing an introductory voiceover to an album by Mr. Bungle, one of Patton's bands. In 2016, DeVito also included music from Patton's band Faith No More on It's Always Sunny in Philidalphia.

DeVito has an extensive film career, dating back to the early 1970s.
