FMW 4th Anniversary Show: Origin was a professional wrestling event produced by Frontier Martial-Arts Wrestling (FMW). The event took place on May 5, 1993 at the Kawasaki Stadium in Kawasaki, Kanagawa, Japan. This was the fourth edition of the company's flagship event Anniversary Show, commemorating the fourth anniversary of the company.

The main event was a no rope exploding barbed wire time bomb deathmatch between Atsushi Onita and Terry Funk, which Onita won. The event was also notable for a Captain's Fall Losing Captain Leaves Town No Rope Barbed Wire Tornado Street Fight Deathmatch pitting Tarzan Goto, The Great Punk and Katsuji Ueda against Team Canada members Ricky Fuji, Big Titan and The Gladiator in a losing effort. The event featured interpromotional matches between female wrestlers of FMW and Ladies Legend Pro-Wrestling (LLPW) and All Japan Women's Pro-Wrestling (AJW).

FMW decided to capitalize on the huge success of the 2nd Anniversary Show on September 23, 1991 at the huge Kawasaki Stadium as the show drew a crowd of 33,000. FMW booked their 4th Anniversary Show at the Kawasaki Stadium on May 5, 1993 to commemorate the fourth anniversary of the company and the huge crowd attraction was a dream match between the company's promoter and main star Atsushi Onita and hardcore wrestling idol Terry Funk. FMW signed Kawasaki Stadium to be the company's venue for future shows on May 5.
