Marine Aviation and Training Support Group 33 (MATSG-33) is a United States Marine Corps aviation training group that was originally established during World War II as Marine Aircraft Group 33 (MAG-33). Fighter squadrons from MAG-33 fought most notably during the Battle of Okinawa and also as the first Marine aviation units to support the Korean War when they arrived as part of the 1st Provisional Marine Brigade. They helped stabilize the United Nations positions during the Battle of Pusan Perimeter and fought in Korea for the remainder of the war. At some point in the 1960s, the group was deactivated and was not reactivated until 2000, when Marine Aviation Training Support Group at Naval Air Station Oceana, Virginia was renamed MATSG-33.

Provide administration and training support to all Marines aboard NAS Oceana. They also provide ceremonial support for base and local events in the form of color guards and special detail advisors. While the MATSG's mission is administrative in nature, the command monitors the flow of students through the Naval Air Training Command, provides Marine Corps discipline and Marine Corps peculiar training

Marine Aircraft Group 33 (MAG-33) was commissioned on February 1, 1943 at Marine Corps Air Station Cherry Point, North Carolina. They moved to Marine Corps Auxiliary Field Bogue on September 27, 1943. On April 6, 1944, the group again transferred, this time to Marine Corps Air Station Eagle Mountain Lake, Texas where they spent the remainder of the summer training. In August, they moved on to Marine Corps Air Station Miramar, California to prepare for their deployment to the South Pacific.
