Andrew Sznajder (born May 25, 1967 in Preston, United Kingdom) is a Canadian former professional tennis player. He reached a career-high ATP singles ranking of No. 46 on September 25, 1989 and a career-high ATP doubles ranking of No. 182 on July 29, 1991.
Sznajder's career-high singles ranking was the highest any Canadian male was ranked in singles by the ATP until Greg Rusedski made it to No. 41 in June 1994 (before becoming a British citizen). Prior to his pro career, Sznajder played college tennis at Pepperdine University for the Pepperdine Waves, and was a two-time All-American selection (1987 and 1988; he was No. 3 in college rankings both years). His .800 won-lost percentage there (40–10) is the 6th-best in the school's history. In 1988, he won the Intercollegiate Tennis Association indoor individual championship. He turned pro in his sophomore year. The summer of 1989 was his best season as a pro. He won the Chicoutimi Challenger event, reached the third round at both the Stratton Mountain and Indianapolis Grand Prix events, the quarterfinals of the Canadian Open and Los Angeles Grand Prix tournament, and the second round of the US Open. In July 1989 he defeated world No. 24 Jay Berger in Stratton Mountain, in August he beat No. 23 Kevin Curren in Montréal and in September he upset No. 8 Tim Mayotte in Los Angeles. In April 1990, Sznajder was a finalist of the Rio de Janeiro Grand Prix event. In November he upset world No. 35 Karel Nováček in Brazil. He retired in 1996.
Sznajder was born in Preston, United Kingdom and moved to Toronto, Ontario, Canada at age seven. Upon retiring from the tour, Sznajder worked as Product Manager at PageNet Canada Inc. for 10 years. He then founded his own tennis health and racquet club software company, and directs his own tennis academy ASTA, and GSM Tennis Club, in Kitchener, Ontario. He continued to play competitively, and captured the 2002 Ontario Indoor Championship. He also became a top-ranking competitor on the ITF sanctioned Senior Circuit Over-35s. He was inducted into the Canadian Tennis Hall of Fame in 2002.
