Harve Presnell (September 14, 1933 – June 30, 2009) was an American actor and singer. He began his career in the mid 1950s as a classical baritone, singing with orchestras and opera companies throughout the United States. His career reoriented away from classical music to musical theatre in 1960 after Meredith Willson cast him in the lead role of his new Broadway musical The Unsinkable Molly Brown. His portrayal of "Leadville Johnny" was a resounding success and he reprised the role in the 1964 film version of the musical, winning a Golden Globe Award for his portrayal.

Presnell went on to star in a few more films during the 1960s, but by the early 1970s that aspect of his career came to a standstill. From 1970 to 1995 he mostly worked as a musical theatre performer on Broadway, the West End, and in touring productions out of New York. In his early 60s, Presnell saw a resurgence in his movie career which lasted until his death. He portrayed character roles in films like Fargo (1996), Saving Private Ryan (1998), and Flags of Our Fathers (2006). He also appeared on television as Mr. Parker in The Pretender and Lew Staziak in Andy Barker, P.I.. He had recurring roles on Lois & Clark: The New Adventures of Superman and Dawson's Creek.
