Ben Edward McLemore III (born February 11, 1993) is an American professional basketball player. He played college basketball for the Kansas Jayhawks.
 McLemore was selected with the seventh overall pick in the 2013 NBA draft by the Sacramento Kings. He spent four seasons with the team before signing with the Memphis Grizzlies in July 2017. He was traded back to Sacramento in July 2018 but was waived in February 2019. In July of the same year, McLemore signed with the Houston Rockets. He signed with the Los Angeles Lakers in April 2021 and joined the Trail Blazers in August of the same year. McLemore signed with the Shandong Hi-Speed Kirin in January 2023.
 McLemore played high school basketball at Wellston High School in St. Louis, Missouri for three years before his school was shut down in 2010. He then attended both Oak Hill Academy in Mouth of Wilson, Virginia and Christian Life Center in Humble, Texas during his senior year of high school.
 Considered a four-star recruit by Rivals.com, McLemore was listed as the No. 9 shooting guard and the No. 34 player in the nation in 2011.
 After committing to Kansas, McLemore was deemed ineligible to play by the NCAA because he attended multiple high schools, resulting in his transcripts being "a little fuzzy". He was allowed to practice with the team and take part in team activities starting in the second semester of the school year.
 At the beginning of his college career, McLemore was considered to be either a late first-round or early second-round prospect. However, during his first season as a redshirt freshman, McLemore averaged 15.9 points, 5.2 rebounds, and 2.0 assists, with 49.5% shooting from the field and 87% shooting from the foul line, and was named a finalist for the John R. Wooden Award.
 After declaring for the 2013 NBA draft, allegations arose that NBA agent Rodney Blackstock had given thousands of dollars in impermissible benefits to McLemore's AAU coach, Darius Cobb, in exchange for Cobb steering McLemore toward certain financial advisers and NBA agents. Lending credence to Cobb's allegations, McLemore had Blackstock on his guest pass list for at least three Kansas home games that season, and subsequently signed Blackstock as his NBA agent. This set of facts caused the launch of an NCAA investigation to determine whether or not Kansas would have to vacate the basketball games in which McLemore played.
