The Diccionari General de la Llengua Catalana by Pompeu Fabra is a Catalan dictionary, first published in fascicles in 1931.

Fabra had published a spelling dictionary (Diccionari ortogràfic) in 1917 based on the official orthographic rules (Normes ortogràfiques), in addition to other works aiming to codify the Catalan language.

Fabra created the dictionary during Primo de Rivera's dictatorship (1923–1930).

Aiming for a modern and genuine language, he refused to include certain unused regional or archaic words.

He consulted with specialists so as to include some specific terminology and neologisms to the dictionary.
