Francesco Acri (Catanzaro, 19 March 1834 – Bologna, 21 November 1913) was an Italian philosopher and historian of philosophy.
After graduating with a degree in jurisprudence at Naples in 1857 and studying Aristotle and Kant at Berlin under Friedrich Adolf Trendelenburg, he became a teacher of the history of philosophy, first at the University of Palermo and then, from 1871 at the University of Bologna, where he remained until 1911.
Bound to Rosminian spiritualism, he engaged in invective with the Hegelians and the positivists, in a long dispute with his predecessor in the Bolognese chair, Francesco Fiorentino.
Politically a clerical, he was elected as a city councilor in Bologna in 1895, he campaigned against divorce and for the introduction of the catechism in schools, and was also a strenuous defender of the participation of Catholics in public life.
Among his major scholarly writings, the translation and commentary on the Dialogues of Plato (various partial editions, collected in three volumes between 1913 and 1915).
His tomb is in the Certosa di Bologna. On the stone dedicated to him, the following memorial is written:
