Mohammad Hassan Mirza Qajar (Persian: شاهزاده محمدحسن میرزا قاجار; 20 November 1899 – 7 January 1943) was a younger brother of the last Qajar Shah of Iran Ahmad Shah Qajar, and former Crown Prince of the Qajar dynasty. Soon after Reza Shah deposed the Qajar dynasty and installed himself as Shah of Iran in 1925, Mohammad Hassan and his family were sent into permanent exile to England. In 1930, he declared himself the rightful heir to the crown as pretender to the throne. He died on 7 January 1943 in Maidenhead, England and was buried in Kerbala, Iraq.
