Trainriders Northeast is a non-profit citizens' organization group based out of Portland, Maine, in the United States.

It was established in 1989 to advocate for the extension of passenger rail service from Boston to Portland and points north.

Today Trainriders Northeast may be most well known for their role in bringing passenger service back to Portland, with the Amtrak Downeaster.

The Maine Eastern Railroad operates a scenic train with service from Brunswick to Rockland, via Bath and Wiscasset.
