Robert Budd Dwyer (November 21, 1939 – January 22, 1987) was an American politician. He served from 1965 to 1971 as a Republican member of the Pennsylvania House of Representatives and from 1971 to 1981 as a member of the Pennsylvania State Senate representing the state's 50th district.

Dwyer then served as the 30th state treasurer of Pennsylvania from January 20, 1981, to January 22, 1987, when he killed himself during a live press conference. In the early 1980s, Pennsylvania discovered that its state workers had overpaid federal taxes due to errors in state withholding prior to Dwyer's administration. A multimillion-dollar recovery contract was required to determine the compensation to be given to each employee.
