Rajiv Mehta was a Starfleet officer in the mid-23rd century.

In the late 2250s, Commander Mehta was the First officer aboard the Pyotr Velikiy-class USS Dauntless under the command of Captain Diego Reyes.

In late-2258 or early-2259, the Dauntless engaged the Klingon Defense Force starship IKS Chech'Iw at Xarant. The conflict cost the lives of 18 crew members, including Commander Mehta. (VAN novella: The Ruins of Noble Men)
