Lawrence J. Simon, better known by the ring name, Boris Malenko, was an American professional wrestler and professional wrestling trainer. He is best known for his appearances with Championship Wrestling from Florida and Big Time Wrestling in the 1960s and 1970s as a Russian heel. He was the father of professional wrestlers Joe and Dean Malenko.

Championship Wrestling from Florida (CWF) was the corporate and brand name of the Tampa, Florida wrestling office existing from 1961, when Eddie Graham first bought into the promotion, until 1987, when it closed down. It is also referred to as Florida Championship Wrestling. When Mike Graham tried a return to promoting, the rights to the name had been acquired by an outside party, forcing him to use another name, Florida Championship Wrestling.
