Achille Locatelli (January 1, 1864 – June 20, 1948) was an Italian painter, mainly of landscapes, and writer of art biographies. He was born in Almenno San Bartolomeo, Province of Bergamo. Among his works were: Un paese del Bresciano; Pioggia; Crepuscolo; Diga sul Brembo; Una giornata d'inverno sul Brembo; Un effetto di sole; and Antica rotonda di San Tommaso in Almenno. He is likely a relative of the culture writer, (born 1856 in Bergamo), who was the father of art critic (born 1883).
