Gary Wayne Coleman (February 8, 1968 – May 28, 2010) was an American actor and comedian. Coleman was the highest-paid child actor on television throughout the late 1970s and 1980s. He was rated first on a list of VH1's "100 Greatest Kid Stars".

Coleman was best known for playing the role of Arnold Jackson in the sitcom Diff'rent Strokes (1978–1986), which he reprised in numerous other television series such as Hello, Larry (1979), The Facts of Life (1979–1980) and The Fresh Prince of Bel-Air (1996), among others. For playing the role of Arnold, he received several accolades, which include two Young Artist Awards; in 1980 for Outstanding Contribution to Youth Through Entertainment and in 1982 for Best Young Actor in a Comedy Series; and three People's Choice Awards; a consecutive three wins for Favorite Young TV Performer from 1980 to 1983; as well as nominations for two TV Land Awards.

Coleman's stardom resulted in several roles thereafter, including his film debut On the Right Track (1981), the comedies Jimmy the Kid and The Kid with the Broken Halo (both released in 1982), the cult film Dirty Work (1998), the satirical-comedy film An American Carol (2008) and the independent film Midgets vs. Mascots (2009). He was the star of The Gary Coleman Show (1982) where he voiced Andy LeBeau, and he additionally provided the voice of Kevin in the animated show Waynehead (1996–1997). He also starred in the video games The Curse of Monkey Island (1997) and did some voice acting and motion capture for Postal 2 (2003).

Coleman struggled financially in later life; in 1989, he successfully sued his parents and business adviser over misappropriation of his assets, only to declare bankruptcy a decade later. Very few details of Coleman's medical history have been made public, although his battles with issues such as growth deficiency, substance abuse, and depression during his life earned significant media coverage.

Coleman died at Utah Valley Regional Medical Center in Provo, Utah on May 28, 2010, aged 42. He had been admitted two days earlier after falling down the stairs at his home in Santaquin and striking his head, resulting in an epidural hematoma.
