Ruhollah Zam (Persian: روح‌الله زم, also Romanized as "Rouhollah Zam"; 27 July 1978 – 12 December 2020) was an Iranian activist and journalist. Best known for operating a Telegram channel named 'Amadnews', which he founded in 2015, Zam played a high-profile role in the 2017–2018 Iranian protests, to which he devoted special coverage at the time. In June 2020, an Iran court found him guilty of "corruption on earth" for running a popular anti-government forum, which officials said had incited the 2017–2018 Iranian protests. He was sentenced to death by an Iranian court and was executed on 12 December 2020.

Ruhollah Zam was born into a clerical family in Tehran in 1978. His father, Mohammad-Ali Zam, is a reformist who served in senior government positions in the 1980s and 1990s. Mohammad-Ali Zam chose the name "Rouhollah" for his son as he was a supporter of Rouhollah Khomeini, founder of the Islamic Republic in Iran, however, Rouhollah later asked his friends to call him Nima. Ruhollah Zam turned against the establishment after the 2009 Iranian presidential election protests, and was imprisoned in Evin Prison for some time. Zam eventually fled Iran to reside in France.

He was best known for operating a Telegram channel named 'Amadnews' (or 'Sedaiemardom', lit. 'Voice of the People'), which he founded in 2015. Zam played a high-profile role in the 2017–18 Iranian protests, to which he devoted special coverage at the time. The Telegram channel's mission is "spreading awareness and seeking justice", and it has about 1.4 million followers. It provided the timing and organizational details of the protests as well as information about officials that challenged the Iranian government. After the Iranian government complained that the channel gave information about how to make gasoline bombs, Telegram shut down the channel in 2018, but it reappeared with a different name. Voice of America's Persian service frequently invited Zam on its broadcasts.

Zam was married to Mahsa Razani and had two daughters.
