Tamiami is a census-designated place (CDP) in Miami-Dade County, Florida, United States. It is part of the Miami metropolitan area of South Florida. The population was 54,212 at the 2020 census.

The name Tamiami is a portmanteau of the phrase "Tampa to Miami". The Tamiami Trail, a roadway that goes through the Everglades, connecting the two cities, was the reason for this combination. The CDP is pronounced the same way its namesake is (the Tamiami Trail), which is "tammy-ammy" (/ˈtæmiˌæmi/), not "tam-my-ammy" (/ˈtæmˌmaɪˈæmi/).

It is bordered to the east by Sweetwater and Westchester, to the southeast by Westwood Lakes, and to the south by Kendale Lakes. U.S. Route 41, the Tamiami Trail, passes through the center of the community, leading east into Miami and west through the Everglades 95 miles (153 km) to Naples. Tampa is an additional 160 miles (260 km) north beyond Naples.
