Lock Me Up is the fourth EP by American rock band the Cab, released April 29, 2014 through Republic Records in the United States.

The week prior to the EP's release, on April 24, Alex Marshall announced his departure from the band.

Upon the EP's release, on April 29 the album was described to have a "poppier/R&B influenced sound" and overall was a "collection of love songs" by Alter the Press.

The opening self-titled track, "Lock Me Up" reverts to the band's themes on Symphony Soldier, having a similar "thumping marching army" vibe.

The final track, "These Are the Lies" experiments with more electronica and dubstep sounds with a piano-driven and violin-influenced opening.
