Johnny Grubb (April 23, 1914 - ) is a former NASCAR driver from Beckley, WV. He competed in five Sprint Cup Series races in his career, earning one top-ten. Grubb's debut came in 1950, when he competed at Darlington in the inaugural Southern 500. Grubb proved to be fast learner, starting 57th in the field of seventy-five but driving to a solid 12th place finish. He continued to impress in three other starts that year, earning a career-best 9th place finish at Langhorne and following that up with an 11th place run at Martinsville and 12th at Hillsboro.
