Silver Service was a brand applied by Amtrak to its long-distance trains running along the United States East Coast between New York City and Miami, Florida.

The two services follow the same general route between New York City and Miami, but diverge between Selma, North Carolina, and Savannah, Georgia, as well as at Auburndale, Florida.

Similarly, the Silver Star ran between Petersburg, Virginia, and Raleigh via the ex-SAL Norlina Subdivision, with a stop at Henderson, North Carolina, until 1985.

Currently, under the Southeast High Speed Rail Corridor plan, the Norlina Subdivision will be rebuilt between Petersburg and Norlina, with both the Silver Star and Amtrak's Charlotte–New York Carolinian being rerouted over the line, with the stop at Henderson being reinstated, as well as a new stop being added at La Crosse, Virginia.

In response to planned rehabilitation work in the East River Tunnels, the Silver Star was temporarily combined with the Capitol Limited on November 10, 2024, forming a Chicago–Washington–Miami through service called the Floridian.
