Rubaldo Merello (16 July 1872 – 31 January 1922) was an Italian painter and sculptor.

Born in Montespluga, a frazione of Madesimo, Merello was the son of a customs inspector.

In 1881 he moved to Genoa with his family, and there Merello trained at the Accademia Ligustica di Belle Arti, graduating in 1892.

[1] Following the disappointment for the rejection of one of his works by the Venice Biennale in 1895, Merello embraced a life of total isolation; in the same years he approached Divisionism, inspired by the works of Plinio Nomellini and Giuseppe Pellizza da Volpedo.

In 1915 he illustrated Sem Benelli's poem Le nozze dei centauri.
