Glen Oaks is a neighborhood in Queens. The neighborhood is part of Queens Community Board 13.
Glen Oaks lies between Grand Central Parkway and Nassau County to the north, Union Turnpike to the south, Queens/Nassau border (Lakeville Road) to the east, and the Cross Island Parkway to the west. In this area, the Queens/Nassau border separates New York City from the Village of Lake Success to the north. The Queens/Nassau border is referred to locally as "the city line" and is so designated on New York City buses. Union Turnpike is the main commercial road in the area.
The northern edge of Glen Oaks is a line of hills which are part of the terminal moraine of the last glacial period. These hills include the highest point in Queens : 258.2 feet (78.7 m) above sea level. The southern part of Glen Oaks is a glacial outwash plain.
The postal Zip Code zones for this area do not follow political boundaries, even crossing the city line. The easternmost part of the neighborhood is the 11040 zip code, addressed as New Hyde Park. The northernmost part of the neighborhood - the North Shore Towers complex- is in the 11005 zip code, addressed as Floral Park. The portion of the neighborhood west of Little Neck Parkway- other than the Queens County Farm Museum- is in the 11426 zip code, addressed as Bellerose. Finally , the central part of the neighborhood is the 11004 zip code, which may be addressed as either Glen Oaks or Floral Park. Since the zip codes cross the city line, they cannot be sued as the sole means to determine sales tax rates.
North of Glen Oaks is the Little Neck neighborhood. The Queens neighborhoods of Bellerose and Floral Park lie south of Glen Oaks. The Nassau County villages of Bellerose and Floral Park lie south of the Queens neighborhoods with the same names. East of Glen Oaks (past Lake Success) is the unincorporated neighborhood of North New Hyde PArk. South of North New Hyde Park is the Village of New Hyde Park. So even though Glen Oaks shares various postal city names with Nassau County villages, it is not adjacent to those villages and is not politically related to them other than being in the same state. The right-of-way of the most historical Long Island Motor Parkway is now the southernmost edge of the parking lot of Green Meadows Farm. East of Little Neck Parkway route is now 74th Avenue, including Tenney Park. The route also defines the southern border of the North Shore Towers complex.
