San Andrés Semetabaj is a municipality in the Sololá department of Guatemala. According to Jorge Luis Arriola's Geonimias de Guatemala, Semetabaj means "stone of glass-like appearance" and originates from the Spanish word "semet", which means: bottle or flask and, by extension, glass, and by the k'akch'iquel "abaj" which means "stone". Originally, it was called San Andrés Limetabaj.
