The University of California, Santa Barbara, often abbreviated as UCSB, is a prestigious research institute in the United States, which specialises in liberal arts. As a Public Ivy university, UCSB is well regarded among US universities.

The roots of UCSB begin with the establishment of the Anna Blake School in 1891. The institution, which firstly taught economics, saw forty years of development and expansion before becoming part of the ten colleges united under the University of California public university system.

UCSB is also home to two professional departments: Bren School of Environmental Science & Management and the Gevirtz Graduate School of Education.
