José Abrego (3 Mar 1813 – 3 April 1878) was a 19th-century Californian merchant. He arrived in Alta California in 1834 as a member of Compania Cosmopolitan A, part of the Hijar-Padrés colony. It was led by José Maria Hijar and Don José Maria Padrés. Abrego became a merchant in Monterey, California, and held a variety of political offices. He served as treasurer of the territory from 1839 to 1846. After the Mexican–American War, he continued to operate as a merchant. He became very wealthy and built a home that is still preserved in Monterey.

Abrego was born in Mexico City, Mexico. He married Maria Josefa Casilda Aniceta Estrada, a native Californio born in Monterey, in about 1836. She was half-sister of California Governor Juan Bautista Alvarado. He died in 1878. One of his sons, Abimael, married Adelaida Leese, daughter of Rosalia Vallejo.
