Omar D'León (1929 – August 26, 2022) was a Nicaraguan painter and poet.
D'León studied nine years at the Escuela Nacional de Bellas Artes in Nicaragua under its director Rodrigo Peñalba [es].
His early inspiration were the frescos of Pompeii, where he saw the use of cross-hatching and applied this technique to his love of the Impressionist school.
The museum's collection encompassed the arts of Nicaragua from pre-Hispanic to contemporary.
1972, D'León's museum and studio were partly destroyed and later ransacked, vandalized and robbed.
