The Keystone Service is a 195 mile (314 km) regional passenger train service from Amtrak, that operates between the Harrisburg Transportation Center in Harrisburg, Pennsylvania, and 30th Street Station in Philadelphia, running along the Philadelphia to Harrisburg Main Line (known as the Keystone Corridor). Most trains then continue along the Northeast Corridor (NEC) to Penn Station in New York City.

Trips between Harrisburg and New York take approximately 3+12 hours, including 1+34 hours between Harrisburg and Philadelphia. There are also several express services that can cut the journey times of both by approximately 15 minutes.

The line is considered higher-speed rail with trains operating at up to 125 miles per hour (200 km/h) over parts of the Northeast Corridor and up to 110 mph (180 km/h) over parts of the Keystone Corridor.

As of 2024 it is Amtrak's fifth-busiest route nationally, and the third-busiest among services in the greater Northeast Corridor, carrying 1.27 million passengers, an increase of 13.7% over FY2023. Total revenue in FY2016 was $41,123,787, an increase of 7.5% over FY2015. The route is primarily funded by the Pennsylvania Department of Transportation (PennDOT).
