Sultan Yahya Petra Ibni Al-Mahum Sultan Ibrahim, GCMG, (10 December 1917 – 29 March 1979) was the sixth Yang di-Pertuan Agong (King) of Malaysia from 21 September 1975 to his death, and twelfth (by some reckoning tenth) Sultan of modern Kelantan (1960–1979).

He was born Tengku Yahya Petra at Istana Balai Besar in Kota Bharu. He was the second son of Sultan Ibrahim ibni Almarhum Sultan Muhammad IV (b. 1897; reigned 1944–1960) but the first by his commoner wife, Cik Embong binti Encik Daud (1899–1971), who was later promoted to the style Che Ampuan Besar by her son.

The young Tengku Yahya Petra was raised by his childless uncle, Tengku Ismail, later Sultan Ismail ibni Almarhum Sultan Muhammad IV. He was sent to the Francis Light School in Penang before continuing his studies in England. His uncle, Sultan Ismail, appointed him Tengku Temenggong on 21 July 1939. He was later promoted to Tengku Bendahara on 6 February 1945 by his father, then Sultan Ibrahim. He served in various Kelantan civil service posts from 1941 to 1948.

Tengku Indra Petra was the eldest son of Sultan Ibrahim and elder brother of Tengku Yahya Petra. After Sultan Ibrahim succeeded his childless brother Sultan Ismail, Tengku Indra Petra had been appointed heir apparent with the title of Raja Muda on 25 October 1944. However, due to conflict with his father, he was dismissed from the post and removed from the line of succession by his father's decree on 1 February 1948. On the same day, Tengku Yahya Petra replaced his brother as heir apparent with the new title of Tengku Mahkota.

Tengku Indra Petra became a politician and was elected a Member of Parliament (MP) in the first federal legislative election of 1955. Tengku Indra's descendants have since disputed their family's exclusion from the line succession of the Kelantan throne.

Tengku Indra Petra did not preside over the installation of Sultan Yahya Petra's successor, Sultan Ismail Petra, It was Tengku Panglima Raja Tengku Ahmad who presided over both installations of Sultan Yahya Petra and Sultan Ismail Petra. Tengku Panglima Raja is the father of the former Sultanah of Johor, Sultanah Zanariah binti Tengku Ahmad.
