Zachary "Zach" Randolph (born July 16, 1981 in Marion, Indiana) is an American professional basketball player currently with the Memphis Grizzlies of the NBA.

Randolph grew up in Marion, Indiana and attended Marion High School, where his coach was Moe Smedley. Zach was mentored by Craig Moore, a teacher at Marion, since he was 12. They are still great friends today. As a sophomore, he helped lead the Marion Giants to the class 4A championship game. As a senior, he again led his team to the state championship game in which Marion High School won its seventh state basketball championship. He finished second in Indiana's 'Mr. Basketball' voting that year, closely behind Jared Jeffries, who coincidentally played for the team that the Giants beat in the state championship game that year and would later become Randolph's teammate with the Knicks.

After high school, Randolph attended and played basketball for the Michigan State University Spartans, coached by Tom Izzo. His teammates at MSU included Jason Richardson and Charlie Bell. In his single season at Michigan State, he averaged 10.8 points and 6.7 rebounds per game over 33 games, with a team that finished with a 28-5 record and went to the NCAA Final Four. After his freshman season he entered the 2001 NBA Draft.
