Josiah Jamison (born August 18, 1982) is a visually impaired American sprint runner. He has retinitis pigmentosa, a hereditary eye disease that affects peripheral and night vision. He began racing at the South Carolina School for the Deaf and Blind in Spartanburg and won a gold medal for the United States at the 2008 Summer Paralympics in the 100 m T12 event. He also competed at the 2012 Summer Paralympics, but was disqualified in both the 100 m and 200 m heats for violating a newly implemented rule that a guide may not separate from the runner farther than 50 cm; his 4 × 100 m relay team also failed to finish at those Paralympics. At the world championships Jamison won a gold, a silver and a bronze medal between 2006 and 2013.
