Manuel Pla i Agustí (c. 1725-1766) was a Spanish (from Catalonia) composer, oboist, and harpsichordist at the court of Madrid. He was the middle of three composer-brothers: his older brother Joan Baptista Pla (1720-1773), settled as an oboist in Lisbon, and his younger brother was Josep (c. 1728 - 1762).
