The M142 High Mobility Artillery Rocket System (HIMARS /ˈhaɪmɑːrz/) is a light multiple rocket launcher developed in the late 1990s for the United States Army and mounted on a standard U.S. Army Family of Medium Tactical Vehicles (FMTV) M1140 truck frame.

The HIMARS carries one pod with either six Guided Multiple Launch Rocket System rockets or one ATACMS missile. It is based on the U.S. Army's FMTV five-ton truck, and is capable of launching all rockets in the Multiple Launch Rocket System Family of Munitions. HIMARS ammunition pods are interchangeable with the M270 MLRS. It has a single pod, as opposed to the standard two for the M270 and its variants.

The launcher can be transported by C-17 Globemaster, C-5 Galaxy, and Lockheed C-130 Hercules aircraft. The FMTV truck that transports the HIMARS was initially produced by Armor Holdings Aerospace and Defense Group Tactical Vehicle Systems Division, the original equipment manufacturer of the FMTV. It was produced by the Oshkosh Corporation from 2010 to 2017, with all units since then being manufactured by Lockheed Martin's Missiles and Fire Control division.
