Round Trip is the debut album by former TNT singer Tony Harnell, released on July 2, 2010, credited to Tony Harnell & The Mercury Train.

Although it is considered a solo album, Harnell says this is not his solo album but rather a project, while his debut solo album is yet to be released.

The album is a collection re-recordings of classic Harnell songs from his previous bands TNT and Westworld, in a new stripped-down acoustic form, along with a new song recorded especially for this release - "Anywhere But Here".

[2] Track 12, "When I'm Away," is listed in the liner notes as a bonus track.

Some copies had a sticker on the cover which mistakenly advertised songs by Starbreaker being included.
