The Ronkonkoma Branch is a rail service operated by the Long Island Rail Road (LIRR) in the U.S. state of New York. On LIRR maps and printed schedules, the "Ronkonkoma Branch" includes trains running along the railroad's Main Line from Hicksville (where the Port Jefferson Branch leaves the Main Line) to Ronkonkoma, and between Ronkonkoma and the Main Line's eastern terminus at Greenport.^[3]^[4] The section of the Main Line east of Ronkonkoma is not electrified and is referred to as the Greenport Branch.

The western segment between Hicksville and Ronkonkoma sees 24-hour service to Penn Station and Grand Central Madison in New York City. The eastern segment between Ronkonkoma and Greenport is served by diesel-electric trains, and only sees a handful of trips each day. The eastern segment is also the only dark territory area of the Long Island Rail Road, meaning that it does not have signals.^[5]
