Ibrahim bin Ismail[1] (Jawi: إبراهيم بن إسماعيل; 19 October 1922 – 23 December 2010) was a Malaysian soldier who served in the British Special Operations Executive (SOE) during World War II, subsequently rising to the post of Chief of the Malaysian Defence Forces from 1970 until 1977.

[2] Their disinformation led the Japanese to believe the land assault on Malaya – Operation Zipper – would occur on the Kra Isthmus, 650 miles (1,050 km) to the north of its actual location.

Japan surrendered before the landings, and Ibrahim informed his captors that his religion would not permit him to commit hara-kiri with them.

In 2000 Ibrahim was appointed a Grand Commander of the Order of Loyalty to the Crown of Malaysia, and received the honorific title "Tun".

[2] Tun Ibrahim died at Tuanku Mizan Armed Forces Hospital, Kuala Lumpur on 23 December 2010.
