Jill Ireland (April 24, 1936 – May 18, 1990) was an English actress.
Born in London, England, Ireland was best known for her many films with her second husband, Charles Bronson, in the 1970s, and for her portrayal of Leila Kalomi in the Star Trek episode "This Side of Paradise".
She was married to Scottish actor David McCallum from May 11, 1957 to 1967 and worked opposite him in The Man From U.N.C.L.E. episode "The Quadripartite Affair" (season 1, episode 3 - 1964) and again four weeks later in episode 7, "The Giuoco Piano Affair". She came back a third time in "The Tigers Are Coming Affair" (episode 37 in 1965). They had three sons, including their adopted son, Jason McCallum, who died of a drug overdose in 1989. His death devastated Ireland and made her into an anti-drug activist during the last year of her life.
