Jonathan Roy Broxton (born June 16, 1984 in Augusta, Georgia) is a Major League Baseball closer for the Los Angeles Dodgers. He bats and throws right-handed. Broxton is known for his velocity, regularly throwing pitches ranging from 98 to 101 mph. On July 3, 2009 against the San Diego Padres he was clocked at 103 mph.

A prototypical fireballer, the 6'4", 290-pound Broxton features an overwhelming fastball as well as a slider. He became the Dodgers closer at the end of the 2008 season when Takashi Saito went down with an injury. Saito was released after the season, clearing the way for Broxton to inherit that role full-time.

Broxton attended Burke County High School in Waynesboro, Georgia. As a senior, he posted a 9-2 record and a 1.21 earned run average as a pitcher.
