San Ignacio Cohuirimpo is a small town and comisaría in the Navojoa municipality, in the Mexican state of Sonora.

San Ignacio was one of the main areas where the "Mayos", the indigenous people of Navojoa, could be found.

At present, it can be considered a part of the metropolitan area, as it has grown urbanely thanks to the work of the municipal government of Navojoa.

The urban public transport routes of Navojoa, named SUBA, don't enter San Ignacio Cohuirimpo.

The closest of them all is the 7th route, which leads to Navojoa's Periférico around San Ignacio.
