The Leonardo Express is an airport rail service linking the center of Rome with its largest airport, Leonardo da Vinci-Fiumicino Airport, in the region of Lazio, central Italy.

The service is operated by Trenitalia, and takes 32 minutes to travel the 37 kilometres (23 mi) between its two stops.

The train station Fiumicino Aeroporto is located inside the airport and is easily accessible.
