138 Tolosa (Latin Tolōsa, /toʊˈloʊsə/ or /toʊˈloʊzə/; [toˈloː.za], [tuˈlu.zɔ]) is a brightly coloured, stony main-belt asteroid. It was discovered by French astronomer Henri Joseph Perrotin on May 19, 1874, and named after the Latin and Occitan name for Toulouse, France.
The spectrum of this asteroid rules out the presence of ordinary chondrites, while leaning in favor of clinopyroxene phases. As of 2006, there are no known meteorites with compositions similar to the spectrum of 138 Tolosa.
