Lennep is a ghost town and populated place in Meagher County, Montana, United States.

Lennep is in the valley that divides the two ranges, that contains the South Fork of the Musselshell River.

A trackside signal can still be seen along Jawbone Road, where train tracks were removed over 30 years ago.

[citation needed] Today Lennep is a sparsely occupied tourist attraction, with a number of buildings remaining and in reasonable condition, including the church, school, and store.

There are still rural residences in the surrounding vicinity of Lennep, including substantial working ranches.
