Quin Walton Houff (born September 15, 1997) is an American professional stock car racing driver.

[1] Houff ran the entire 2015 CARS Super Late Model Series schedule at age seventeen.

He won one race, in Hudson, North Carolina, recorded four more top fives and finished fourth in points.

[12] On March 21, 2017, it was announced that Houff would drive two NASCAR Xfinity Series races for Precision Performance Motorsports, at Bristol Motor Speedway and Richmond International Raceway.

[14] At Bristol, Houff hovered around the top ten most of the day after a strong qualifying run but damage due to an incident with Ross Chastain dropped him to fifteenth.

[20] After finishing 31st in a one-off for the team, a deal came together on October 18, 2018 for Houff to run the final four races of the Xfinity Series season in the organization's No.

[24] At the 2020 O'Reilly Auto Parts 500 at Texas, Houff made a last-minute decision to enter pit-road with 29 laps to go, clipping the cars of Christopher Bell and Matt DiBenedetto in the process before crashing into the outside retaining wall.

He was later on criticized by DiBenedetto and Brad Keselowski, who proposed that NASCAR should add a relegation structure that would demote developmental drivers to the lower divisions should they commit a mistake similar to Houff's.

[25] Later that season, in the 2020 Yellawood 500 at Talladega Superspeedway, he finished a career high 13th place after avoiding multiple accidents on the ending laps.
