Wong Ah Kiu (1918 – 19 January 2006), legally known as Nyonya binti Tahir, was a Malaysian woman born to a Muslim family but raised Buddhist.

[1] The court case which arose after her death over whether she should receive an Islamic funeral or a Buddhist one brought up various issues regarding freedom of religion in Malaysia.

[1][3] The head of the Negeri Sembilan Religious Affairs Department came to her family's house in person to present the order that she be buried in the Muslim fashion.

Wong was buried next to her husband in the Chinese cemetery in her birthplace of Simpang Ampat, Alor Gajah.

Later commentators attributed the favourable outcome to the family's attitude of co-operation with the court, contrasting the ruling with that given on M. Moorthy, a member of the first Malaysian team to scale Mount Everest.
