Charles Edward O'Bannon Jr. (born March 1, 1999) is an American college basketball player for the TCU Horned Frogs of the Big 12 Conference. He previously played for the USC Trojans.

O'Bannon was born to Valencia and Charles O'Bannon, who was playing professional basketball.^[1] O'Bannon lived in Japan from ages 2 to 14 with his parents while his father was playing there.^[2]

O'Bannon attended Bishop Gorman High School in Las Vegas, Nevada. He averaged 21.4 points as a senior at Bishop Gorman. In December 2016, he committed to the USC Trojans. He chose USC over UNLV, NC State, and UCLA.^[3] He was named a McDonald's All-American.^[1]

O'Bannon was the first McDonald's All-American to join USC since DeMar DeRozan in 2008.^[4] He struggled with injuries during his two and a half seasons with the Trojans. After suffering an injury to his left pinky finger that required surgery, he redshirted the 2018-19 season. O'Bannon injured his middle finger early in the following season and played three games. He played a total of 18 games at USC and averaged 1.8 points and 0.8 rebounds per game. In January 2020, O'Bannon transferred to TCU and was later granted a waiver for immediate eligibility.^[5]

In 2021–22, TCU was a No. 9 seed in the 2022 NCAA tournament, and earned their first NCAA Tournament win in 35 years. O'Bannon scored a career-high 23 points in a second-round loss to Arizona, ending the Horned Frogs bid to reach the Sweet 16 for the first time.^[6]

O'Bannon's father, Charles, and uncle, Ed O'Bannon, were teammates on UCLA's 1994–95 national title team.^[2]
