Franz Clemens Honoratus Hermann Josef Brentano (/brɛnˈtɑːnoʊ/; German: [bʁɛnˈtaːno]; 16 January 1838 – 17 March 1917) was a German philosopher and psychologist. His 1874 Psychology from an Empirical Standpoint, considered his magnum opus, is credited with having reintroduced the medieval scholastic concept of intentionality into contemporary philosophy.

Originally a Catholic priest, Brentano withdrew from the priesthood in 1873 due to the dogmatic definition of papal infallibility in Pastor aeternus. Working subsequently as a non-denominational professor, his teaching triggered research in a wide array of fields such as linguistics, logic, mathematics and experimental psychology through the young generation of philosophers who were gathered as the School of Brentano.
