Una '''basa azotada''' es un [[compausat organic]] que gracia a sos proprietats de [[Basa (quimia)|basa]] a un [[parelh solitari]] d'[[electron|electrons]] d'un [[atòm]] d'[[azòt]]. Las basas azotadas principalas son l'[[adenina]], la [[guanina]], la [[timina]], la [[citosina]] e l'[[uracil]], fan partida del [[material genetic]], mas trobam tanben las [[amina]]s coma l'[[amòni]] (NH<sub>3</sub>), la [[trietilamina]], la [[piridina]].
Las basas azotadas se pòdon classificar en dos grops: [[purina]]s, adenina (A) e guanina (G); e [[pirimidina]]s, citosina (C), timina (T) e uracil (U). Aquelas basas forman la part principala dels [[nucleotid]]s, e las interaccions entre la adenina/timina e la guanina/citosina son la basa del [[còde genetic]] universal. En l'[[ARN]] l'uracil substituissi la timina.
