|Title:||Asymptotic Giant Branch Stars in Local Group Galaxies and their importance for the Distance Scale|

I will review recent work on large amplitude variables in Local Group galaxies and discuss their potential as distance indicators. These cool stars, which are very luminous at near- and mid-infrared wavelengths, are important producers of dust, but have not yet been properly incorporated into the theoretical models of stellar evolution. The Local Group offers interesting opportunities to study them in different environments.
