Matthew Jacob Hong (born September 4, 1991) is an American rock climber, filmmaker and photographer.

[5] After earning a Bachelor of Fine Arts in Film Production at the University of Colorado Boulder,[6] Hong climbed his first 5.15a (9a+) route, Papichulo 5.15a (9a+) in Oliana, Spain, in March 2016.

[9] In October 2021, Hong completed the second-ever ascent of Flex Luthor, first sent by Tommy Caldwell in 2003.

Hong suggested the grade be revised to 5.15b (9b) from 5.15a (9a+) after multiple holds broke making the climb harder.
