Second Wind is a 1976 Canadian sport comedy film, directed and edited by Don (Donald) Shebib, written by Hal Ackerman, and produced by James Margellos. This was the first feature film starring role for actor James Naughton, who portrays a stock broker whose new jogging hobby turns into an obsession to excel at long distance running, straining his career and his relationship with his wife (Lindsay Wagner).

The film is Shebib's fourth feature. Commercially unsuccessful, reviews of Second Wind were mixed, tending to praise the cinematography and acting, but usually faulting the script. Second Wind won a Canadian Society of Cinematographers award and two Canadian Screen Awards.
