Ladies and Gentlemen... Mr. Leonard Cohen is a 1965 National Film Board of Canada documentary about Leonard Cohen, co-directed by Don Owen and Donald Brittain, written by Brittain and produced by John Kemeny.

The documentary captures Cohen's career as a noted poet and novelist before he launched his career as a singer-songwriter in 1967. The original idea for the film had involved documenting a tour of Canadian poets, including Irving Layton and Earle Birney; however, that idea was abandoned when the filmmakers decided the other poets would not serve as charismatic film subjects.
