La toba volcánica o tufo volcánico es un tipo de roca ígnea volcánica, ligera, de consistencia porosa, formada por la acumulación de cenizas u otros elementos volcánicos muy pequeños expelidos por los respiraderos durante una erupción volcánica. Se forma principalmente por el depósito de cenizas y lapilli durante las erupciones piroclásticas. Su velocidad de enfriamiento es más rápida que en el caso de rocas intrusivas como el granito y con una menor concentración en cristales. No hay que confundirla con la toba calcárea ni tampoco con la pumita.
