Peter Chan Chun-chuen (born 23 December 1959), earlier known as Tony Chan, is a Hong Kong businessman and the former Feng shui geomancer to the late Nina Wang, who at the time of her death was chair of Chinachem Group and Asia's richest woman.

[9] After Nina Wang's death in 2007, Chan presented a 2006 document purporting to be her last will and testament, which left all of her assets to him.

This would have been a complete reversal of Wang's earlier 2002 will, in which she stated that she wished to bequeath her fortune to Chinachem Charitable Foundation, a trust run by her family.

On 2 February 2010, the Hong Kong High Court ruled that Wang's estate belonged to the Foundation and not to Chan.

[14] Hong Kong's Inland Revenue Department issued a demand for HK$300 million in back taxes on income he is alleged to have received from Wang for feng shui services, sums which Chan claims were gifts from his lover.
