Mare Island Naval Shipyard Airfield was a post-World War 1 US Navy airfield that opened around 1922 and closed in 1937 at Mare Island Naval Shipyard in the city of Vallejo, California. The airfield was located at 13th Street & Flagship Drive on the naval base, just west of the Marine Barracks (Building M37). The airfield had a single unpaved runway for day use only. Common aircraft at the airfield were Vought FU, Vought VE-7 and Curtiss JN-4 Jenny.{{Cite web|url=https://www.airfieldsfreeman.com/CA/Airfields_CA_Oakland.htm#mareisland|title=Abandoned & Little-Known Airfields: Oakland area|website=Abandoned & Little-Known Airfields}}

The first aviation activity at Mare Island took place as early as 1919, when three Mather field Army Air Corps planes landed on and took off from the Marine Parade Ground. The first Naval aviation at Mare Island took place in August 1923, when several Navy planes arrived at the airfield while the aircraft tender Aroostook had set up some temporary hanger-sheds.{{cite book |last1=Lott |first1=Arnold S. |title=A Long Line of Ships: Mare Island's Century of Naval Activity in California |date=1954 |publisher=United States Naval Institute |location=Annapolis, MD |url=https://books.google.com/books?id=gCQZAAAAIAAJ&q=%22arnold+s+lott%22+aroostook}}{{rp|176,185}}

The airbase at Mare Island was established as a support base for the first US Navy aircraft carrier, {{USS|Langley|CV-1|6}}, which had her origin at Mare Island. The collier USS Jupiter, the first turbo-electric-powered ship of the US Navy, was built at Mare Island Naval Shipyard in 1912 and was later converted into the first US aircraft carrier, USS Langley, at Norfolk Naval Shipyard, Portsmouth, Virginia during 1920-1922. During the next decade and a half, she would visit Mare Island Naval Shipyard at least two times. As converted, Langley could hold up to 34 planes, but her planes need to be removed to the Airfield whenever she was at the Shipyard for overhauls or refittings.{{cite book |last1=Lemmon |first1=Sue |last2=Wichels |first2=E.

Her first overhaul at Mare Island Naval Shipyard was in 1925, when her flight deck was lengthened by {{cvt|23|ft}} and her complement of airplanes was increased to two full squadrons (36 aircraft) on deck with six more stored below.{{cite web |last1=Johnson |first1=Frank |title=USS Langley: The U.S. Navy's Covered Wagon |url=https://warfarehistorynetwork.com/article/uss-langley-the-u-s-navys-covered-wagon/ |website=Warfare history network |access-date=4 July 2024 |date=December 2022}} In 1928 the catapult on her front deck was removed. Langley's last visit to Mare Island Naval Shipyard was between October 1936 and February 1937, when she was converted again, this time to a seaplane tender.{{rp|30-31}}

The airfield was also used for training. The Mare Island Naval Shipyard Airfield was disestablished in 1937 when nearby Naval Air Station Alameda was officially picked to be the Navy's main support base for aircraft carriers in San Francisco Bay.
