Edwin James Costa (August 14, 1930 – July 28, 1962) was an American jazz pianist, vibraphonist, composer and arranger. In 1957 he was chosen as Down Beat jazz critics’ new star on piano and vibes – the first time that one artist won two categories in the same year. He became known for his percussive, driving piano style that concentrated on the lower octaves of the keyboard.

Costa had an eight-year recording career, during which he appeared on more than 100 albums; five of these were under his own leadership. As a sideman he appeared in orchestras led by Manny Albam, Gil Evans, Woody Herman and others; played in smaller groups led by musicians including Tal Farlow, Coleman Hawkins, Gunther Schuller, and Phil Woods; and accompanied vocalists including Tony Bennett and Chris Connor. Costa died, aged 31, in a car accident in New York City.

Eddie Costa was born in Atlas, Pennsylvania, near Mount Carmel, in Northumberland County. He was taught and influenced on piano by his older, musically trained brother, Bill, and a local piano teacher. Eddie took paid jobs as a pianist from the age of 15. In contrast to his piano training, he was self-taught on vibes. In 1949 Costa played and toured for a few months with violinist Joe Venuti. He then worked for his brother in New York until, in 1951, Eddie was drafted into the army. During his time in the armed forces, Costa performed in Japan and Korea. Upon release after two years, Costa again worked around the New York area, including for bands led by Kai Winding, Johnny Smith, and Don Elliott.
