The PFL 5 mixed martial arts event for the 2018 season of the Professional Fighters League was held on August 2, 2018, at the Nassau Coliseum in Uniondale, New York. This is the fifth regular season event of 2018 and included only fights in the lightweight and light heavyweight divisions.

Background
Brian Foster was expected to face Natan Schulte at this event. However, Foster was removed due to an unspecified illness and replaced by Jason High.

Originally a fight was set between Islam Mamedov and Efrain Escudero. However, Escudero missed the 156-pound weight limit by over seven pounds, and the bout was scratched from the card all together. As a result, Mamedov was awarded 3 points via walkover victory.
