Peter Lim Eng Hock (born 21 May 1953) is a Singaporean business magnate who was a stockbroker and an investor in palm oil, and is now a private investor focused on healthcare, property, sports, and education. In 2024, he was ranked 26th on Forbes' list of Singapore's 50 Richest with a net worth of US$1.75 billion. He was a shareholder of English club Salford City until 2024 and has been the owner of Spanish La Liga club Valencia CF since 2014.

In 2010, Lim won the biggest libel payout in Singapore's history in the Raffles Town Club saga.

The son of a fishmonger, Lim and his seven siblings grew up in a two-bedroom government flat in the Bukit Ho Swee public housing estate. Lim completed his secondary school education at the Raffles Institution. After National Service, he went to Perth to study at the University of Western Australia. To fund his university education, Lim worked part-time doing odd jobs as a taxi driver, cook and waiter.

While working at Australian fast-food chain Red Rooster, Lim studied how businesses are started, how they grow, and how they scale up.

He graduated with a degree in accounting and finance and first worked in accountancy and tax consultancy before going into stocks.

In the early 1990s, Lim invested about US$10 million in a start-up palm-oil company, Wilmar. In 2010, Lim cashed out at the peak of commodity prices and sold his Wilmar shares for US$1.5 billion.

Lim was known as the "Remisier King" (commission king) due to his success as a stockbroker in the 1980s.

Lim quit the brokerage business in 1996 and became a private investor.
