Antonio María Romeu Marrero (11 September 1876 – 18 January 1955) was a Cuban pianist, composer and bandleader.

[2][3] Romeu studied music in 1884 with Joaquín Mariano Martínez, and practiced the piano at a local church by the beach in Jibacoa.

The initial line-up for Orquesta Romeu featured Romeu on piano, Feliciano Facenda on violin, Alfredo Valdés on flute, Rafael Calazán on double bass, Remigio Valdés on timbales, and Juan de la Merced on güiro.

He arranged many famous works of the trova, Cuba's singer/songwriter tradition, such as "Guarina" and "Perla marina" (Sindo Garay), "Mares y arenas" (Rosendo Ruiz), "Mercedes" (Manuel Corona), "Aquella boca" (Eusebio Delfín) and "La cleptomanía" (Manuel Luna).

In addition, he adapted classical works such as "La flauta mágica" (from Mozart's The Magic Flute) and "El barbero de Sevilla" (from Rossini's The Barber of Seville).
