XHNZI-FM is a radio station on 99.1 FM in Nacozari, Sonora, Mexico, known as La Reina de la Sierra.
The concession for XHNZI was awarded on October 28, 1994, to Javier Moreno Valle, a Mexico City businessman who would found XHTVM-TV in Mexico City and a Ciudad Juárez radio station.
The station's concession passed to Claudia Elena Lizárraga Verdugo in 2008. Grupo Radio Guaymas transferred operation of the station to Grupo Larsa Comunicaciones, a dominant radio broadcaster in Sonora, in 2017; Larsa immediately dropped the La Reyna del Cobre name and format for its own Toño adult hits format.
In 2023, the station ceased to be operated by Larsa. Grupo Radio Guaymas resumed operating XHNZI as La Reina de la Sierra ("Queen of the Mountains").
