Sayyid Assadollah Ladjevardi (Persian: اسدالله لاجوردی; 1935 – 23 August 1998) was an Iranian conservative politician, prosecutor and warden.

Later in 1970, he served three years in Evin prison for attempting to blow up the offices of El Al (the Israeli airline) in Tehran.

Finally, he was once again arrested and sentenced to 18 years in prison, for being a member of the opposition militant group People's Mujahedin of Iran.

In her memoir, Iran Awakening, Nobel Peace Prize Laureate Shirin Ebadi states that an estimated 4000-5000 members and supporters of the People's Mujahedin of Iran (MKO) were executed during a three-month period in 1988 immediately following the failed "Mersad" rebellion, which was launched upon the end of the Iran–Iraq War by MKO fighters based in Iraq.
