Theodore “Fats” Navarro (September 24, 1923 – July 6, 1950)^[1] was an American jazz trumpet player. He was a pioneer of the bebop style of jazz improvisation in the 1940s. He had a strong stylistic influence on many other players, including Clifford Brown.

Navarro was born in Key West, Florida, United States, of Cuban, African, and Chinese descent. He began playing piano at age six, but did not become serious about music until he began playing trumpet at the age of thirteen. He was a childhood friend of drummer Al Dreares. By the time he graduated from Douglass High School, he wanted to be away from Key West and joined a dance band headed for the Midwest. Navarro died of tuberculosis and heroin addiction in New York City on July 6, 1950, and was survived by wife Rena (née Clark, 1927–1975) and his daughter Linda (1949–2014). He was buried in an unmarked grave, number 414, at the Rose Hill Cemetery in Linden, New Jersey.
