Abdollah Riazi (Persian: عبدالله ریاضی) was an Iranian politician who served as the Speaker of the Parliament of Iran for almost 15 years during the Pahlavi dynasty.

[3] According to Ali Rahnema, Riazi was "one of permanent and trusted figures" in the establishment, thus "experienced and adept at political correctness".

[4] Fakhreddin Azimi describes Riazi as having an "unquestioning deference toward the Shah", which "contrasted sharply with his disdainful attitude toward the deputies, whom he treated virtually as schoolchildren".

He was then elected as member of the executive committee and Speaker of the Majles (Parliament or Congress) for the first time.

[5] Following the Iranian Revolution, he was arrested and faced three charges in the Islamic Revolutionary Court, including "corruption on earth", "collaborating with the former regime and trying to re-establish the Shah's idolatrous rule over the weak and defenceless people" and "treason"; eventually leading to execution.
