Diving at the 1948 Summer Olympics – Men's 3 metre springboard

The men's 3 metre springboard, also reported as springboard diving, was one of four diving events on the diving at the 1948 Summer Olympics programme.

The competition, held on Friday July 30 and on Tuesday August 3, was split into two sets of dives:

1. Compulsory dives
2. Facultative dives

Twenty-seven divers from 16 nations competed. Eddie Heron of Ireland competed in the preliminary round but withdrew along with the rest of the Irish Amateur Swimming Association squad in protest at FINA's refusal to allow swimmers from Northern Ireland to compete for the team.
