Marco Osorio (born 1 April 1972) is a former professional tennis player from Mexico.

He played Davis Cup for the first time in 1998, when the Mexican team went to Cali to compete against Colombia and lost 2–3. His only appearance came in the doubles, which he and partner David Roditi lost in a five set match. In 1999 he featured in two further ties for Mexico, wins over Paraguay and Cuba. He played both singles rubbers in each of the ties and won the decisive fifth rubber to defeat Cuba, over Sandor Martínez-Breijo.
