Epifanio Obdulio "Epy" Guerrero (January 3, 1942 - May 23, 2013) was a Dominican baseball scout who signed more than 50 Major League Baseball (MLB) players for the Houston Astros, New York Yankees, Toronto Blue Jays and Milwaukee Brewers. Epy was the brother of former shortstop Mario Guerrero, and had two sons, Epy Jr. and Mike, who played minor league ball.

Guerrero was a Toronto Blue Jays coach in 1981. As a Blue Jays scout, Guerrero signed Tony Fernández and Carlos Delgado, and urged upper management to draft George Bell away from the Philadelphia Phillies.

He is considered to have signed more major leaguers than any other scout, including All Stars Cesar Cedeño, Carlos Delgado, Tony Fernández, Dámaso García, Alfredo Griffin, and José Mesa.

Guerrero was inducted into the Dominican Sports Hall of Fame in October 2008, and on January 15, 2009, Guerrero received a "Legends in Scouting Award" from the Professional Baseball Scouts Foundation.
During the 40 years Guerrero scouted for the Astros (1963–1973), Yankees (1974–1976), Blue Jays (1977–1995) and Brewers (1996–2003), 52 of the players he signed eventually reached the major leagues.
