The Abbas Mirza Mosque (Armenian: Աբաս Միրզայի մզկիթ, romanized: Abas Mirzayi mzkit; Persian: مسجد عباس میرزا) was a seventeenth-century Twelver Shia Islam mosque, that was located in what is modern-day Yerevan, Armenia.

Rebuilt in c. 1817 in Qajar Iran, due to the neglect of first the Russian tsarist and then the Soviet authorities, the mosque gradually fell into disrepair, constant looting disfigured the interior and façade,[1] and the remains of the mosque were finally demolished in the late 1980s.

The façade of mosque was covered in green and blue glass,[2] reflecting Persian architectural styles.

It stands a little east of the old palace; the interior beneath the spacious dome is decorated with much skill by means of little bricks of many colours.

An old henna-stained attendant informed us that it was erected in the reign of Fath Ali Shah and that it was known as the Abbas Mirza Jami.
