Richard Paul Kiley (March 31, 1922 - March 5, 1999) was an American stage, television, and film actor. He is best known for his voice work, as narrator of various documentary series, and for having played Don Quixote in the original 1965 production of the Broadway musical Man of La Mancha. Kiley was the first who sang and recorded The Impossible Dream, the now-classic hit song from the show. In the 1953 hit musical Kismet, he played the Caliph, and introduced the song Stranger in Paradise.

In Jurassic Park, the park's impresario boasts about the tour of the park, "The voice you're now hearing is Richard Kiley. We've spared no expense." Kiley was introduced as the narrator for the tour first in the novel by Michael Crichton, and later in the film adaptation by Steven Spielberg. Visitors to Universal's Islands of Adventure theme park in Orlando, Florida and Universal Studios in Hollywood hear Kiley as the narrator of the Jurassic Park Adventure Ride.

Kiley was born in Chicago, Illinois and raised Roman Catholic. His work on stage included Richard Rodgers's first musical for which he wrote both music and lyrics, No Strings, the Buddy Hackett vehicle I Had a Ball, and the lead roles in Redhead and Man of La Mancha. He won Tony Awards as Best Actor in a musical for the latter two. The dual role of the middle-aged Miguel de Cervantes and Don Quixote is one of the few musical roles which is both a character actor role and a leading man at the same time, rather than the conventional handsome hero who wins the girl, and Kiley, who had gone on record as saying that he had grown tired of the regular "leading man" role, was always grateful for having been given the chance to play it. Although he did not star in the film version of Man of La Mancha, his performance led to many made-for-TV films and guest shots. He was one of the few actors on Broadway who had both a fine singing voice and exceptional acting ability.

Kiley won several Emmy Awards and Golden Globe Awards for his work in television, including The Thorn Birds (as Paddy, Rachel Ward's father) (1983) and A Year in the Life (1986, 1987-1988).

Kiley appeared as Gideon Seyetik in the Star Trek: Deep Space Nine episode "Second Sight".

Kiley died of an unspecified bone marrow disease in Warwick, New York at the age of 76. The lights on Broadway theaters were turned off in his honor.

Although Richard Kiley's rich, baritone, and strong vocal talent was much in evidence and received due respect with his award of a Tony for "Man of La Mancha", it was little used in his television and movie appearances. Won two Tony Awards as Best Actor (Musical): in 1959 for "Redhead" and in 1966 for his signature role, "Man of La Mancha". He was also nominated in the same category in 1962 for "No Strings" and, in 1987, as as Best Actor (Play) for a revival of Arthur Miller (I)'s "All My Sons".
