Sheikh Abdullah bin Husayn bin Nasser al-Ahmar was a Yemeni politician and tribal leader. He was the Speaker of the House of Representatives (Yemen) from 1993 to 2007 and also was the Sheikh of the Hashid tribal federation and the Al-Islah party.

The Hashid is a tribal confederation in Yemen. It is the second or third largest – after Bakil and, depending on sources, Madh'hij – yet generally recognized as the strongest and most influential. According to medieval Yemeni genealogies, Hashid and Bakil were the sons of Jashim bin Jubran bin Nawf Bin Tuba'a bin Zayd bin Amr bin Hamdan. Member tribes of the Hashid Confederation are found primarily in the mountains in the North and Northwest of the country.
