Abdullah Saleh al-Ashtal

Abdullah Saleh Al-Ashtal (; 1938 – 26 August 2004) was a Yemeni diplomat who was a permanent representative at the United Nations in New York City for nearly 30 years.

In his early career, he served as the Yemeni ambassador to Brazil.

On 29 May 1973, Al-Ashtal was appointed as the Permanent Representative of South Yemen to the United Nations. In March 1990, he was President of the United Nations Security Council. After South Yemen and North Yemen united on 22 May 1990, Al-Ashtal continued to represent the united Yemen at the UN. He was again President of the Security Council in December 1990.

He is perhaps most well known for being the only member of the United Nations Security Council to oppose authorising military action against the Iraqi invasion of Kuwait. This prompted U.S. ambassador to the UN Thomas Pickering to tell Al-Ashtal: "That will be the most expensive 'no' vote you ever cast". Following this vote, the United States suspended worth of aid to Yemen and Saudi Arabia deported thousands of Yemeni labourers from its borders.
