Thon Marial Maker is a South Sudanese-Australian professional basketball player for Al Riyadi Club Beirut of the Lebanese Basketball League (LBL). He attended high school at Orangeville District Secondary School and played basketball for Canada's Athlete Institute. He was picked 10th overall in the 2016 NBA draft, and played for three different NBA teams between 2016 and 2021.

The 2016 NBA draft was held on June 23, 2016, at Barclays Center in Brooklyn. It was televised nationally in the U.S. by ESPN, and was live streamed for the first time in NBA draft history by The Vertical. National Basketball Association (NBA) teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The draft lottery took place during the playoffs, on May 17, 2016. This was the first time since the lottery system was introduced in 1985 that all NBA teams that missed out on the playoffs remained in the exact spots they were designated, meaning the 10-win/72-loss Philadelphia 76ers received the No. 1 pick, the Los Angeles Lakers kept the No. 2 pick, the Boston Celtics via the Brooklyn Nets got the No. 3 pick, and everyone else stayed in their same spots based on the regular season standings from the 2015–16 season.
