Flowerfield was a station along the Port Jefferson Branch of the Long Island Rail Road in Saint James, New York.
The station opened in 1910 on a parcel purchased by John Lewis Childs to grow plants and seeds, which was later acquired by the Gyrodyne Company of America. The second floor of the station was used by Childs and contained a large sun parlor. The station agency closed in 1944. On July 2, 1959, the LIRR petitioned the New York State Public Service Commission for permission to discontinue all passenger services and team tracks at the station.
Reopening the Flowerfield station, along with a closure of the St. James station, was proposed in the mid-1990s as part of a plan to redevelop the Gyrodyne site.
