Max Blumenthal is an American author, journalist, and blogger. He is a senior writer for Alternet and formerly a writer for The Daily Beast, Al Akhbar, and Media Matters for America. He is the author of two books including Republican Gomorrah: Inside the Movement that Shattered the Party (2009), which appeared on The New York Times bestsellers list, and Goliath: Life and Loathing in Greater Israel (2013).

Blumenthal joined Lebanon's Al Akhbar in late 2011 primarily to write about Israel-Palestine issues and foreign-policy debates in Washington, noting, upon leaving in mid-2012 in protest of its coverage of the Syrian Civil War, that it "gave me more latitude than any paper in the United States to write about ... Israel and Palestine". He ended his association with Al Akhbar in June 2012, over what he viewed as the newspaper's pro-Assad editorial line during the Syrian Civil War that he said was spearheaded by Amal Saad-Ghorayeb.

Blumenthal contributes weekly articles to Alternet where he has been a senior writer since September 2014. He focuses on the deepening crisis in the Middle East and its role in shaping political dynamics and public opinion in the US, particularly the special relationship with Israel. He occasionally covers domestic issues such as corporate media consolidation, the influence of the Christian right and police brutality. His reporting from the Gaza strip in 2014 was developed into a book, The 51 Day War: Ruin and Resistance in Gaza.

Blumenthal's articles and video documentaries have appeared in The New York Times, Los Angeles Times, The Daily Beast, The Nation, The Guardian, The Huffington Post, Independent Film Channel (IFC), Salon, The Real News, and Al Jazeera English, among other publications.
