Fernando Arbello (May 30, 1906 – July 26, 1970) was a prominent Puerto Rican jazz trombonist and composer, known for his extensive career in the United States. Born in Ponce, Puerto Rico, Arbello was the second of seven children to Eladio Arbelo and Raimunda Cruz. He began playing the trombone at the age of 12 and further honed his skills at the Puerto Rico Conservatory of Music in Ponce. His early musical experiences included performing in high school bands and local symphony orchestras.

In the mid-1920s, Arbello moved to New York City, where he embarked on a successful career, performing with notable musicians such as Earle Howard, Wilbur De Paris, June Clark, and Bingie Madison. Throughout the 1930s, he played intermittently with Claude Hopkins and collaborated with other jazz legends like Chick Webb, Fletcher Henderson, Lucky Millinder, Billy Hicks, and Fats Waller.

In 1940, Arbello briefly led his own band and worked with Zutty Singleton. He continued to collaborate with Henderson and joined Marty Marsala and Jimmie Lunceford's ensembles during the early 1940s. Although he led his own band again in the late 1940s, he never recorded with this group. His later career included performances with Rex Stewart and a reunion with Henderson in 1953, as well as a stint with Machito in 1960.

Arbello returned to Puerto Rico in the late 1960s and led a band at the Hotel San Juan in 1969. He frequently visited New York and, during one such visit in 1970, fell ill and died of a heart attack in the Bronx. Arbello is buried in Ferncliff Cemetery and was survived by his wife, six children, and grandchildren.
