XHERK-FM is a radio station on 104.9 FM in Tepic, Nayarit.

By the 1960s, it was owned by Julián Tomás Mondragón Prieto, now with 1,000 watts on 860 kHz.

Many of these stations are now part of Radiorama Nayarit after Radiorama began operating the stations itself, with Korita maintaining XHERK and XHSK-FM in Ruiz.

XERK's longtime name was Radio Korita, now used as the corporate name for the business, though it is no longer the name for XHERK-FM.

On March 4, 2019, XHERK flipped to the Los 40 format from Radiópolis.
