Maghsoudbeyk Mosque (Persian: مسجد مقصودبیک) is near the northeastern corner of Naqsh-e Jahan Square.

It was built in 1601 by the order of Maghsoudbeyk, who was one of the very rich stewards of Abbas I.

There is an inscription in the mihrab of this mosque, which is one of artworks of the famous calligrapher of the Safavid era Ali Reza Abbassi.

Behind the entrance hall of the mosque in a small chamber, there's a tomb which is the tomb of Mir Emad, the art rival of Ali Reza Abbassi.
