The Morelos satellites are a series of Mexican communications satellites. The first two operated between 1985 and 1998 and provided telephony, data, and television services over the territory of the Mexican Republic and adjacent areas. The third is now part of the MEXSAT constellation (sister ship of the MEXSAT-1 lost during launch) but carries the Morelos name.

The original Morelos satellites were replaced by the Solidaridad Satellite System (Solidaridad I, launched 17 November 1993, and Solidaridad 2, launched 17 October 1994) and, following privatisation, by the Satmex Satellite System.
