Joseph Phillip Vigorito (November 10, 1918 – February 5, 2003) was a Democratic member of the U.S. House of Representatives for Pennsylvania from 1965 to 1977.

In 1964, Vigorito was elected to Congress from a district based in Erie as part of the gigantic Democratic landslide of that year.

He was reelected five more times before being defeated in 1976 by Mercer County Solicitor Marc L. Marks.

During his time in office, Nina Totenberg named Vigorito one of the ten dumbest members of Congress.

Since his loss, one Democrat, Kathy Dahlkemper, represented Erie County for one term from 2009 to 2011.
