The Oklahoma State Cowboys and Cowgirls are the intercollegiate athletic teams that represent Oklahoma State University, located in Stillwater. The program's mascot is a cowboy named Pistol Pete. Oklahoma State participates at the National Collegiate Athletic Association (NCAA)'s Division I Football Bowl Subdivision (FBS) as a member of the Big 12 Conference. The university's current athletic director is Chad Weiberg, who replaced the retiring Mike Holder on July 1, 2021. Oklahoma State has won 55 national championships, including 53 NCAA team national titles, which ranks sixth in most NCAA team national championships. These national titles have come in wrestling (34), golf (11), cross country (5), basketball (2), and baseball (1), and the Cowboys also claim non-NCAA national titles in football (1) and equestrian (1). In addition, Oklahoma State athletes have won 183 individual national titles.

Prior to 1957, Oklahoma State University was known as Oklahoma A&M. As was common with most land-grant schools, its teams were known for many years as the Aggies, though they were sometimes also called the Tigers. However, in 1923, A&M was looking for a new mascot to replace its pet tiger (the inspiration behind the school colors of orange and black). A group of students saw famed cowboy Frank Eaton leading the Armistice Day parade. He was approached to see if he would be interested in being the model for the new mascot, and he agreed. The caricature adopted his nickname "Pistol Pete".

Only a few decades removed from the cattle drive era, the cowboy was still an important figure in the Southwest. The new mascot had become so popular that by 1924, Charles Saulsberry, sports editor of The Oklahoma Times, began calling A&M's teams the "Cowboys". "Aggies" and "Cowboys" were used interchangeably until A&M was elevated to university status in 1957. In 1958, the "Pistol Pete" caricature was formally adopted as Oklahoma State's mascot, though it had been used unofficially for over three decades before then.

The "Waving Song" is one of the fight songs for Oklahoma State. At Oklahoma State football games, the song is played by the Cowboy Marching Band during the pregame traditions, following touchdowns, and after victories against the Cowboys' opponents. For other athletic events, the Waving Song is played after Oklahoma State victories as the start of the fight song trilogy. While the song is played, fans wave their right arms in the air; the effect is similar to wheat waving in the wind.

The song's melody is that of "The Streets of New York", a song from the Victor Herbert operetta, The Red Mill. The lyrics used by Oklahoma State were written by H.G. Seldomridge, a professor at what was then Oklahoma A&M who heard the tune on a visit to New York City. It was first sung in 1908 at a follies show at Stillwater's Grand Opera House. Ever since, it has been a tradition to play the song at Oklahoma State athletic events. The only real change over the years has been to replace "OAMC" with "Oklahoma State".

Oklahoma A&M was a founding member of the Southwest Conference. In 1925, they moved to the Missouri Valley Intercollegiate Athletic Association. Three years later, the conference split with the six largest schools forming the Big Six and Oklahoma A&M remaining with three smaller schools to form the Missouri Valley Conference. In 1956, Oklahoma A&M went independent in anticipation of an invitation to join the Big Seven (an enlarged Big Six). In June 1957, the recently-renamed Oklahoma State officially joined the Big Seven, which was renamed the Big Eight. However, Oklahoma State did not compete as part of the conference until the 1958–59 season for basketball and the 1960 season for football. Because both the MVC and the Big Eight claimed to be the direct successor of the MVIAA, some consider Oklahoma State's move to the Big Eight as rejoining the conference.

Oklahoma State first took the basketball court in 1908. Under head coach Henry Iba, the team won NCAA championships in 1945 and again in 1946. A&M center Bob Kurland was named the NCAA Tournament MVP during their two championship seasons. Kurland was the first player to win the honor two times.

They have won a total of 23 conference championships, with 3 of those coming in the Big 12.

Under Eddie Sutton, the team made two Final Four appearances—in 1995 and in 2004. Sutton's son, Sean Sutton, began coaching the team in 2006 but resigned on March 31, 2008. The team is now coached by Steve Lutz, who was hired to the head coach position after Mike Boynton Jr was fired following the 2023-24 season.

Oklahoma State first fielded a women's team during the 1972–1973 season. The Cowgirls have been to 17 NCAA tournaments, and have made 3 Sweet 16s.

Oklahoma State has won 26 conference tournament titles to go along with 25 regular season conference titles, including 16 consecutive conference championships (1981-1996) under head coach Gary Ward in the Big 8 Conference. During that time, Pete Incaviglia was named Baseball America's Player of the Century, and Robin Ventura was inducted in the inaugural class into the College Baseball Hall of Fame. Overall, Oklahoma State has made 20 College World Series appearances, including seven straight from 1981 to 1987.

Oklahoma State men's cross country is one of the most illustrious cross country programs in the nation, winning NCAA national championships in 1954, 2009, 2010, 2012, and 2023.

There have been 7 Cowgirls who have been crowned individual Big 12 champion, with Taylor Roe becoming the first Big 12 individual conference champion from OSU when she won in 2023, breaking a 34 year drought. At the 2023 NCAA Cross Country Championships, Oklahoma State claimed a 3rd place finish, only 33 points behind the winners, the best finish ever for the women's cross country team. 24 Cowgirls have won the All-American award, and 2 Olympians have hailed from OSU. The Cowgirls run at the Greiner Family OSU Cross Country Course, and are led by 5x Big 12 Women's Coach of the Year, Dave Smith.

They have also had NCEA title success, winning 4 NCEA Western national titles in 2003, 2004, 2006 and 2013. However, they were unable to win the overall national title until 2022, when they defeated Texas A&M 11-9 to claim their first NCEA Dual Discipline national title.

Gundy coached the team to a record 12 win season in 2011, culminating with a Fiesta Bowl victory over Stanford, and ten years later led Oklahoma State to another 12 win season and Fiesta Bowl victory, this time over Notre Dame. His accolades consist of the 2011 Eddie Robinson National Coach of the Year, 2011 Paul "Bear" Bryant National Coach of the Year, and the 2011 American Football Monthly National Coach of the Year.

Oklahoma State wrestling's tradition started in 1916 when Edward C. Gallagher, whose name is part of Gallagher-Iba Arena, became head coach. With his expertise in anatomy, he pioneered the sport of wrestling. Gallagher coached the Cowboys until his death in 1940 from pneumonia. During those 24 years, Gallagher had 11 team national titles, 19 undefeated seasons, and a 138–5–4 record.

After Gallagher's death, Art Griffith took over and proceeded to win two straight national championships. Due to World War II, Oklahoma State wrestling was forced off the mat for three years. After the war, Griffith coached for another 11 years and won six more national championships in that time. Due to health reasons, Art Griffith resigned as head coach and Myron Roderick took over. At 23 years old, Roderick became the youngest coach to win a national championship in 1958. Roderick proceeded to win another 5 championships. In 1970, Myron Roderick stepped down to take an executive position with the U.S. Wrestling Federation.
