Coconut Grove, also known colloquially as The Grove, is an affluent and the oldest continuously inhabited neighborhood of Miami in Miami-Dade County, Florida. The neighborhood is roughly bounded by North Prospect Drive to the south, LeJeune Road to the west, South Dixie Highway (US 1) and Rickenbacker Causeway to the north, and Biscayne Bay to the east. It is south of the neighborhoods of Brickell and The Roads and east of Coral Gables. The neighborhood's name has sometimes been spelled "Cocoanut Grove", but the definitive spelling "Coconut Grove" was established when the city was incorporated in 1919. What is today referred to as Coconut Grove was formed in 1925 when the city of Miami annexed two areas of about equal size, the city of Coconut Grove and most of the town of Silver Bluff. Coconut Grove approximately corresponds to the same area as the 33133 ZIP Code, although the ZIP Code includes parts of Coral Way and Coral Gables. The area is often referred to as "The Grove", and many locals take pride that Coconut Grove is one of the greenest areas of Miami. Coconut Grove is directly served by the Miami Metrorail at Coconut Grove and Douglas Road stations.
