James "Buffalo Jim" Barrier (March 22, 1953 – April 6, 2008), born in Buffalo, New York, was an American wrestling promotor in Las Vegas. His legal struggle with business owner and landlord Frederick "Rick" Rizzolo, who owned the property under Barrier's business, Allstate Auto & Marine, was covered by the media during the early 2000s.

Barrier moved to Las Vegas in 1971, at age 18, from Cleveland, Ohio. He later opened his auto repair shop on Industrial Road, which he operated until his death. In the 1980s and '90s, he owned Buffalo Jim's Professional Wrestling School and had a local paid-for TV wrestling show, "Jim Wars," that aired on Friday nights. Also, he wrote a weekly column, "Nuts and Bolts with Buffalo Jim" on auto repair for the now-folded Las Vegas Mercury.

Barrier over the years met many celebrities, including Hulk Hogan and Muhammad Ali. He also had a large collection of celebrity memorabilia, from vehicles to a lock of Elvis's hair. Included in this collection were cars -- a Jensen Interceptor -- that used to belong to Wayne Newton and a pink Cadillac of Kid Rock's used during the rocker's proposal to Pamela Anderson.
