Catch wrestling (also known as catch-as-catch-can) is an English wrestling style with fewer restrictions than other wrestling styles. It allows techniques using or targeting the legs (unlike Greco-Roman wrestling), it allows joint locks (unlike freestyle wrestling and Greco-Roman wrestling), and there are no mandatory grips. It was spread by wrestlers of travelling funfairs who developed their own submission holds, referred to as "hooks" and "stretches", into their wrestling to increase their effectiveness against their opponents, as well as immigrants through Europe and the Anglosphere.

Catch-as-catch-can was included in the 1904 Olympic Games and continued through the 1936 Games; it had new rules and weight categories introduced similar to other amateur wrestling styles, and dangerous moves – including all submission holds – were banned. At the amateur level, FILA developed and codified new rules and regulations to replace catch wrestling with freestyle wrestling, which was then considered separate from the dangerous, professional catch style. After a revival effort starting in the 1980s, competitive catch wrestling gradually made a return, leading to The Snake Pit's Catch Wrestling World Championships and notable competitions such as the Snake Pit British Championships and ACWA US Open.

William Alfred Robinson (18 September 1938 – 27 February 2014) was an English professional wrestler, amateur wrestler, catch wrestler, and wrestling coach. Having trained at Billy Riley's gym, better known as "The Snake Pit" in Wigan, Robinson was one of the leading practitioners of catch wrestling, a British national champion in freestyle wrestling, and a professional wrestling world champion. He had a successful career in the UK and internationally, especially in Japan.

Robinson is known for training professional wrestlers and mixed martial artists in the catch wrestling style, including Josh Barnett, Kazushi Sakuraba, Kiyoshi Tamura, and Shayna Baszler. His favourite saying as a coach was "do it again", which came from his trainer Billy Riley. He acted in several movies, including The Wrestler, and inspired the Kinnikuman character Robin Mask.
