The Imamzadeh Haroun-e-Velayat (Persian: امامزاده هارون ولایت), or the Harun-i Vilayat Mausoleum, is an imamzadeh in Isfahan, Iran. It is located opposite the Ali minaret in Dardasht and belongs to the Ismail I era. There are many accounts of Harun Vilayat, the person who is buried in it. Some say that he is the seventh Imam's son and others, that he is the tenth Imam's son, but aside from the matter of who is buried in it, it is the most important historical structure related to the early Safavid era. Beyond the tomb it has also a portico, a tiled dome and a large yard.

It seems that some repairs and improvements were carried out in the Fath-Ali Shah era.

The mausoleum has become a shrine reputed to have miraculous powers and is also venerated by some Armenian Christians.
