Peter Sweeney was an early 20th-century Scottish-American soccer forward who began his professional career in Scotland before playing in the National Association Football League and American Soccer League in the United States.
In October 1916, he was on the roster of Babcock & Wilcox which played in the National Association Football League.
On April 19, 1921, Sweeney scored Robin's third goal in a 4–2 victory over St. Louis Scullin Steel F.C.
This move brought the merger Robins Dry Dock and Tebo Yacht Basin F.C., both sponsored by subsidiary companies of Todd Shipyards into a larger Todd Shipyards team.
That year, he moved to the Jersey City team, but played only two games before he left the league.
