Philip David Swing (November 30, 1884 – August 8, 1963) was an American Republican politician from Imperial County, California.
His single-minded determination resulted in 1928 in the Swing-Johnson Act, co-sponsored by Sen. Hiram Johnson, which authorized Boulder Dam.
The project brought water to Southern California and enabled San Diego to grow and prosper.
In 1933, as one of his last acts in Congress, he introduced a bill to establish Anza-Borrego Desert State Park, which passed in March.
A water fountain at the Community Concourse at Third and C Streets is dedicated to Phil Swing, "The Father of Boulder Dam."
