Abstract: Dwarf galaxies in the Local Group constitute a good representation of dwarfs outside its border in the nearby Universe. In the near infrared most of the brightest stars in these galaxies are on the AGB and can be studied in some detail on an individual basis. This allows for tests of models of the late stages of stellar evolution, as well as providing information on the star formation history in the parent galaxies. Some AGB stars are Mira variables, for which an infrared period-luminosity relation exists, though distance estimation is not entirely straightforward thanks to the reddening produced by copious mass loss from some of these stars. This review will focus on our current understanding of the photometric characteristics of AGB stars in the Local Group and of prospects for discovery as investigations push well beyond its boundary in the near future.
