Johnny Pulado Estrada III (born June 27, 1976) is an American former professional baseball catcher, who played in Major League Baseball (MLB) for the Philadelphia Phillies, Atlanta Braves, Arizona Diamondbacks, Milwaukee Brewers, and Washington Nationals.

After Javy López left due to free agency, Estrada became Atlanta's starting catcher in 2004.

Estrada also made the All-Star team and helped Atlanta win their 13th division title in a row.
