José Francisco Capellán (born on January 13, 1981 in Cotuí, Dominican Republic) is a relief pitcher in Major League Baseball who currently plays for the Colorado Rockies. Previously, Capellán played with the Detroit Tigers, Atlanta Braves and Milwaukee Brewers. He bats and throws right-handed. He throws a fastball that has been clocked at 100 MPH.

In 2004, Capellán pitched at Class-A, Double-A and Triple-A and posted a combined 14-5 mark with a 2.80 ERA. In three 2004 games with the Atlanta Braves after a September call-up, Capellán compiled a 0-1 record with an 11.25 ERA in 8.0 innings.

A highly-touted prospect, Capellán was acquired after a rapid rise through the Braves' system in exchange for All-Star reliever Dan Kolb.

Capellán opened the 2005 season with the Triple-A Nashville Sounds, and was called up to Brewers major league club, where he worked relief through the 2005 season. At the end of spring training in 2007 he was sent back to Triple-A after a poor spring, and demanded a trade and even considered retirement. His wish eventually came true on July 1, 2007, when he was traded to the Detroit Tigers for minor league pitcher Chris Cody.

Capellán was traded from Detroit Tigers to Colorado Rockies in exchange for pitcher Denny Bautista on December 4, 2007.
