Marc Jason Kroon (born April 2, 1973) is an American former right-handed relief pitcher. He served as the closer for the Yomiuri Giants of Japan's Central League.

Draft and minor leagues
He was drafted 72nd overall by the New York Mets in 1991. The Mets traded him to the San Diego Padres in 1993 as the player to be named later in an earlier trade for Frank Seminara.

San Diego Padres (1995, 1997–1998)
On July 7, 1995, Kroon made his Major League debut with the San Diego Padres.

Cincinnati Reds (1998)
The Padres traded Kroon to the Cincinnati Reds for Buddy Carlyle in April 1998.

Kroon retired following elbow surgeries and did not play baseball at any level in 2001 or 2002. He came out of retirement and joined the Anaheim Angels organization in 2003 after coach Mike Butcher's brother-in-law saw him giving a pitching lesson in a park.

Yokohama BayStars (2005–2007)
Kroon joined the Yokohama BayStars in 2005. After the 2007 season, Kroon and the BayStars failed to come to terms on a new contract, and ended up being a free agent.
