Ionel Gherea, also known as Ioan Dobrogeanu-Gherea or Ion D. Gherea (Francized J. D. Ghéréa; 1895 – November 5, 1978), was a Romanian philosopher, essayist, and concert pianist. The son of Constantin Dobrogeanu-Gherea, a Marxist theoretician and critic, and the brother of communist militant Alexandru "Sașa" Gherea, he discarded their political and literary influence, being more interested in the aestheticism of his brother-in-law, Paul Zarifopol. As a youth, Zarifopol took him to meet playwright Ion Luca Caragiale and his family. Gherea's debut as a writer was a 1920 novel written jointly with Luca Caragiale, which was also his only contribution to the genre.
