Liv and Maddie is an American comedy television series created by John D. Beck and Ron Hart. It premiered on Disney Channel on July 19, 2013, and concluded after four seasons on March 24, 2017, with the episode "End-a-Rooney", which was also the series' eightieth episode. The series stars Dove Cameron, Joey Bragg, Tenzing Norgay Trainor, Kali Rocha, Benjamin King, and Lauren Lindsey Donzis.

A significant feature of the series is that Dove Cameron plays dual roles, one being Liv, an actress who has returned to her home after starring on a popular television series in Hollywood for four years, and the other one being Maddie, Liv's identical twin who remained behind. Another significant feature of the series are documentary-style cutaways where characters speak to the viewers to explain their opinions on various situations in each episode.

Actress Liv Rooney is a girly girl who has just returned to her birthplace of Stevens Point, Wisconsin, after finishing a four-year stint in Hollywood, filming a popular television series called Sing It Loud! Her identical twin sister, Maddie, a tomboy with a facility for sports and a particular talent for basketball, welcomes Liv back home with open arms. The twins have two younger brothers: Joey, a typical awkward teen who is one year younger than the twins, and Parker, a clever tween with a mischievous personality and the youngest child of the Rooney family. Their parents are Karen, the high school psychologist and later the high school's vice principal, and Pete, the coach of Maddie's high school basketball team who later accepts a position as the coach of a college team in Beloit, Wisconsin. The series revolves around Liv adjusting to normal family life after her successful career in Hollywood. Most events take place at the Rooney residence or at Ridgewood High School. At the end of the third season, the Rooney house collapses and Maddie enrolls in a college in Los Angeles, California. This prompts the rest of the Rooneys, except Pete who remains in Wisconsin to continue his coaching job, to move to Malibu, California, to take up residence with Karen's younger sister, Dena, and her daughter, Ruby, where the series' fourth season takes place.

Liv and Maddie began production in April 2013. The series was created by John D. Beck and Ron Hart, both of whom also serve as executive producers alongside Andy Fickman. Beck and Hart are a production-writing team whose credits include According to Jim, Hey Arnold!, and Shake It Up!. Originally, the pair had shopped a script of a project called Bits and Pieces which featured a blended family similar to series like The Brady Bunch and Step by Step. The series is produced under a joint venture by Beck & Hart Productions, Oops Doughnuts Productions, and It's a Laugh Productions.

On January 13, 2014, Disney Channel renewed Liv and Maddie for a 13-episode second season slated to premiere in fall 2014. The second season was later expanded to 24 episodes. The second season premiered on September 21, 2014. The series was renewed for a third season by Disney Channel on April 3, 2015. The third season premiered on September 13, 2015. On December 21, 2015, actress Dove Cameron stated that Disney Channel was picking up Liv and Maddie for a fourth season. On June 19, 2016, series co-creator Ron Hart announced on Twitter that the fourth season would premiere in fall 2016. On July 1, 2016, Dove Cameron stated that they had filmed the series' final episode. On August 19, 2016, it was announced by the series' creators, John D. Beck and Ron Hart, that the final season would be called Liv and Maddie: Cali Style. They also stated that the fourth and final season would premiere on September 23, 2016.

Casting took place during the spring of 2012; however, only a pilot episode was produced. The series followed Kali Rocha, Dove Cameron, Joey Bragg, Benjamin King, Cozi Zuehlsdorff, and Tenzing Norgay Trainor portraying Jodie Sullenger, mother of Alanna and Sticky, who married Pete Fickman, father of Crystal and Brody, with all six adjusting to life under the same roof. Eventually, Disney chose to change the concept of Bits and Pieces into one about a pair of twins. Instead of hiring a new cast, production chose to keep those whom they had already hired and film a completely new pilot. The story now focused on Dove Cameron playing dual roles with the same parents and brothers. Lead billing for Cozi Zuehlsdorff was later dropped to guest star. The family name of "Rooney" was picked because of Sullenger's enjoyment of the Pittsburgh Steelers, a team owned by the Rooney family.

A full version of the Liv and Maddie theme song, "Better in Stereo", was recorded by Dove Cameron and released as a promotional single by Walt Disney Records on October 15, 2013. A music video was filmed and aired on Disney Channel the night of October 29, 2013. The song was featured twice in the show, first in the season three finale, "Californi-a-Rooney", and then an acoustic version sung by Dove Cameron during the season four and series finale, "End-a-Rooney".

Neil Genzlinger of The New York Times compared the series to The Patty Duke Show while describing it as "a gentle, moderately amusing comedy" and praising Dove Cameron's portrayal of the down-to-earth Maddie and diva Liv, stating: "...the premise gives the writers plenty of opportunities."
