John William Carson (October 23, 1925 – January 23, 2005) was an American television personality, comedian, writer and producer best known as the host of NBC's The Tonight Show Starring Johnny Carson (1962–1992). Carson received six Primetime Emmy Awards, the Television Academy's 1980 Governor's Award and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987. Carson was awarded the Presidential Medal of Freedom in 1992 and received a Kennedy Center Honor in 1993.

During World War II, Carson served in the United States Navy. After the war he started a career in radio, then moved to television and took over as host of the late-night talk show Tonight from Jack Paar in 1962. Carson remained an American cultural icon even after his retirement in 1992. He adopted a casual, conversational approach with extensive interaction with guests, an approach pioneered by Arthur Godfrey and previous Tonight Show hosts Paar and Steve Allen but enhanced by Carson's lightning-quick wit. Former late-night host and friend David Letterman, as well as many others, have cited Carson's influence. Carson is widely regarded as the king of late-night television.
