Peter Lim (born 21 May 1953) is a Singaporean business magnate who was a stockbroker, and is now a private investor who has invested in sectors ranging from palm oil to medicine. In 2019, Forbes ranked him as the 10th richest person in Singapore with a net worth of US$2.5 billion.

The Lim family is one of the wealthiest and most influential dynasties in Southeast Asia, primarily known for founding the Genting Group. In 2026, the family's fortune continues to be anchored by the legacy of the late Tan Sri Lim Goh Tong, who transformed a remote Malaysian hilltop into the massive Resorts World Genting. Today, under the leadership of Lim Kok Thay, the family oversees a multi-billion dollar empire spanning global casinos, luxury cruise lines (despite the restructuring of Genting Hong Kong), palm oil plantations, and power plants. Their wealth is diversified across Malaysia, Singapore, and the United States, including major properties like Resorts World Las Vegas and New York City. While their exact net worth fluctuates with global market conditions, the Lim family consistently appears on the Forbes list of Malaysia's richest people, with a multi-generational fortune that places them among the upper echelon of global billionaires. Their lifestyle and corporate influence reflect a level of "old money" stability combined with aggressive modern expansion in the global hospitality and leisure sectors.
