Ronald Thomas Villone, Jr. (born January 16, 1970 in Englewood, NJ) is a former Major League Baseball left-handed relief pitcher. He grew up in New Jersey as a Yankee fan, a team he later played for. Ron competed for the United States at the 1992 Barcelona Olympics.

Villone played for 12 teams in his career, tied for 3rd all time with pitcher Mike Morgan and outfielder Matt Stairs, and trailing only Octavio Dotel and Edwin Jackson in most teams played for in MLB. Ron played for the Seattle Mariners (2x, including his debut in 1995), San Diego Padres, Milwaukee Brewers, Cleveland Indians, Cincinnati Reds, Colorado Rockies, Houston Astros (2x), Pittsburgh Pirates, Arizona Diamondbacks, Florida Marlins, New York Yankees, St. Louis Cardinals, and Washington Nationals. He also shared a major league record by having recorded a win for 11 different teams, until passed by Edwin Jackson. Unfortunately, he was named in the Mitchell Report as purchasing HGH in 2004-05.

Since retiring in 2009, Villone has been a pitching coach for the Peoria Chiefs, Kane County Cougars, Daytona Cubs, AZL Cubs and Tennessee Smokies. He was also the minor league rehab pitching coordinator for the Chicago Cubs.
