Dinner Key is a marina complex in the Coconut Grove neighborhood of Miami, Florida along the shore of Biscayne Bay on South Bayshore Drive. It was originally an island, but was connected to the mainland in 1914 by filling in the intervening space. An early source attributes the name to the fact that the island was a convenient place to stop to eat while traveling by boat between the mouth of the Miami River and Snapper Creek south of Miami. Dinner Key is accessible by public transit via the Coconut Grove Circulator from the Miami Metrorail at Coconut Grove and Douglas Road stations.
