Greg Johnson is a former American football coach. He served as the head football coach at Langston University from 1992 to 1996 at and Prairie View A&M University from 1997 to 1998, compiling a career college record of 36–49.
Johnson was the 19th head football coach for the Prairie View A&M University Panthers located in Prairie View, Texas and he held that position for two seasons, from 1997 until 1998. His career coaching record at Prairie View was 1 wins, 19 losses, and 0 ties. As of the conclusion of the 2007 season, this ranks him 19th at Prairie View in total wins and 21st at Prairie View in winning percentage (.050).
Johnson's first 12 consecutive losses played a part in the worst losing streak in NCAA history of 80 games between 1989 and 1998. However, it was in the fourth game of his second season as head coach when the streak was broken by a 14-12 victory over Langston University. Tensions over the losing streak had grown so high at the school that the entire marching band was suspended by the conference the week before as a result of fighting between marching bands.
