XHACM-FM was a radio station on 104.5 FM in Cárdenas, Tabasco, Mexico, known as Éxitos 104.5 FM with tropical and grupera music. It was owned by Armando Calderón Lara (RACLASA).

The station’s history goes back to XEJAC-AM, which received its concession on February 5, 1969 and began on 1110 kHz as a 1 kW daytimer named after its founder, Juan Antonio Calderón Landero. In 1987 the concession was transferred to a new owner, and nighttime service at 100 W began. In the 1990s the station moved to 910 kHz, with 5 kW day and 1 kW night, and the call sign changed to XEACM-AM, honoring Aquiles Calderón Marchena. XEACM was approved to migrate to FM on June 4, 2010, becoming XHACM-FM 104.5.

On January 15, 2021, Armando Calderón Lara surrendered the concession for economic reasons, citing a drop in government advertising and the cost of electoral advertising requirements. The station ceased operations on January 31, 2021. It had an effective radiated power of 6 kW, with the transmitter located at 17°59′10″N 93°23′06″W.
