Xavier Cugat (Catalan: [ʃəβiˈe kuˈɣat]; 1 January 1900 – 27 October 1990) was a Spanish musician and bandleader who spent his formative years in Havana, Cuba. A trained violinist and arranger, he was a leading figure in the spread of Latin music. In New York City he was the leader of the resident orchestra at the Waldorf–Astoria before and after World War II. He was also a cartoonist and a restaurateur. The personal papers of Xavier Cugat are preserved in the Biblioteca de Catalunya.

Cugat was born Francisco de Asís Javier Cugat Mingall de Bru y Deulofeu in Girona, Catalonia, Spain. His family emigrated to Cuba when he was three years old. He studied classical violin and worked as a violinist at the age of nine in a silent movie theater to help pay for his education. He was first chair violinist for the Teatro Nacional Symphonic Orchestra. When he wasn’t performing, he started drawing caricatures. On 6 July 1915 he and his family arrived in New York City on the SS Havana. Cugat appeared in recitals with Enrico Caruso, playing violin solos.
