John Christopher Brown (August 15, 1961 – December 26, 2006) was an American third baseman in Major League Baseball during the 1980s, most notably with the San Francisco Giants.

In his first full season in 1985, Brown batted .261 with 16 home runs and 61 runs batted in (RBIs) for the last-place Giants, made the All-Rookie team, and finished fourth in the National League Rookie of the Year voting; Brown also led the NL in times being hit by pitch (11).

That offseason, an examination by Dr. Frank Jobe in Los Angeles discovered that there was indeed a serious problem, and surgery was performed that winter.

The following season, with Brown hitting a paltry .242 after 38 games, the Giants sent him packing on July 5 along with Keith Comstock, Mark Davis, and Mark Grant in a midseason trade to the San Diego Padres in exchange for Kevin Mitchell, Dave Dravecky, and Craig Lefferts.

Brown died at Memorial Hermann Hospital in Houston on December 26, 2006, nearly a month after he suffered burns in a fire at a vacant house he owned in Sugar Land, Texas.
