Aldemaro Romero (March 12, 1928 – September 15, 2007) was a Venezuelan pianist, composer, arranger and orchestral conductor. He was born in Valencia, Carabobo State.

Romero was a prolific composer, creating a wide range of music, such as Caribbean, Jazz, Venezuelan waltzes, including works for orchestra, orchestra and soloist, orchestra and choir, chamber music, and symphonic works. He began his musical studies with his father, Rafael Romero. In 1941, he moved to Caracas and worked as pianist in nocturnal saloons and dance orchestras. In 1949, he toured in Cuba, and then went to New York. In 1952, he returned to Caracas and established his own dance orchestra. In 1951, Romero became an arranger at RCA Victor in New York. As a part of this contract, he released his record-breaking Dinner in Caracas album, the first of his Dinner In… series featuring popular Latin American music. In the United States, he collaborated with many musicians, including Dean Martin, Jerry Lee Lewis, Stan Kenton, René Touzent, Machito and Tito Puente. He also toured extensively, performing in various countries: Mexico, Puerto Rico, Colombia, Peru, Brazil, Argentina, Spain, France, Greece, Switzerland, Sweden, Italy, Russia, Egypt and Japan. Romero is considered the creator of the Venezuelan “New Wave” (Onda Nueva) genre, derived from the joropo and Brazilian Bossa Nova. In the 1970s, Romero recorded in Italy La Onda Maxima (1972) and Onda Nueva Instrumental (1976) with bassist/arranger Pino Presti and drummer Tullio De Piscopo. In addition to his work in popular music, Romero was also involved in concert music. He founded the Caracas Philharmonic Orchestra in 1979, and was its first conductor. He also guest conducted the London Symphony Orchestra, the English Chamber Orchestra, the National Radio Orchestra of Romania and the Royal Philharmonic Orchestra.
