Mahan Esfahani (Persian: ماهان اصفهانی ) is an Iranian-American keyboardist; he is the first harpsichordist named as a BBC Radio 3 New Generation Artist. As a concerto soloist, recitalist, and collaborative musician, he has gained an international reputation on a variety of early keyboards.

Born in 1984 in Tehran, Esfahani grew up in United States. While at Stanford University, Esfahani studied musicology and came most seriously under the influence of the American scholar George Houle. Later, he continued his harpsichord studies with the Australian harpsichordist Peter Watchorn in Boston and with the Italian organist Lorenzo Ghielmi in Milan, and benefited from the advice and guidance of the Czech harpsichordist Zuzana Růžičková. Unlike the mainstream of harpsichordists concertising today he has largely diverged from the school of Gustav Leonhardt, though he does cite him as an important spiritual influence.

Having quickly gained an international reputation without the benefit of going through the customary competitions, played many significant concerts, he has been praised as "exceptionally gifted" (The Times) and for "the virtuosity of a master" (Keyboard Magazine)., currently he is as Artist-in-Residence at New College, Oxford. He made his Wigmore Hall debut in 2009 as a concerto soloist with The English Concert, and in the same year performed at the BBC Proms' chamber series and made extensive recordings of concerto and solo repertoire for the harpsichord for BBC Radio 3. Further afield, he made his New York debut at the Frick Collection in 2012.
