Swell Guy is a 1946 American drama film directed by Frank Tuttle and starring Sonny Tufts, Ann Blyth and Ruth Warwick.

The film's screenplay by Richard Brooks is based on the 1921 play The Hero by Gilbert Emery.

Jim stays at his family's home for months for free, tricks people into paying his way, gambles and romantically pursues socialite Marian Tyler, even though she is seeing another man, Mike O'Connor.

Others continue to mistakenly believe Jim to be a nice guy, including his brother and also Tony, a nephew who idolizes him.

Jim saves him just in time, but at the cost of his own life, leaving friends and relatives remembering him as "a swell guy."
