Thomas Raymond Johnson (born April 2, 1951 in Saint Paul, Minnesota) was a Major League Baseball pitcher. He played five seasons in the majors, from 1974 until 1978 for the Minnesota Twins. He pitched in 129 games during his career, all but one as a reliever.
Johnson was signed as an undrafted free agent in 1970. After four years in the Twins' minor league system, he made his major league debut on September 10, 1974. Johnson racked up twenty-three wins as a starter, then later a closer, over five years with the Twins, including sixteen in 1977.
After the 1978 season, Johnson was released, and signed a year later by the Chicago White Sox. He became a starter for the White Sox triple-A affiliate in Glens Falls, but was largely unsuccessful. After the 1980 season, Johnson retired at the age of twenty-nine.
