Ma Huateng (Chinese: 马化腾; pinyin: Mǎ Huàténg, born on October 29, 1971), also known as Pony Ma, is a Chinese business magnate, investor, and politician. He is the founder, chairman and chief executive officer of Tencent, Asia's most valuable company, one of the largest Internet and technology companies, and the biggest investment, gaming and entertainment conglomerates in the world. The company develops China's biggest mobile instant messaging service, WeChat, and its subsidiaries provide media, entertainment, payment systems, smartphones, internet-related services, value-added services and online advertising services, both in China and globally.

In 2007, 2014, and 2018, Time magazine called him one of the world's most influential people, while in 2015, Forbes credited him as one of the world's most powerful people. In 2017, Fortune ranked him as among the top businessmen of the year. In 2018, he was named one of the "Most Powerful People In The World" by the CEOWORLD magazine. Ma is a deputy to the Shenzhen Municipal People's Congress and is a delegate in the 12th National People's Congress.

Being one of "Fortune world's greatest leaders", Ma is known for his low profile personality as compared to fellow Chinese businessman and Alibaba founder Jack Ma's outgoing personality. Ma has been closely compared to American investor Warren Buffett for their similar investment philosophies, and often described as an "aggressive acquisitor".

As of July 2020, he is China's richest man, surpassing Jack Ma, with a net worth of US$59.9 billion according to Forbes. On 21 November 2017, his estimated net worth briefly surpassed that of Larry Page and Sergey Brin (individually) ranking him the ninth richest man in the world at the time, and the first citizen from the People's Republic of China to enter Forbes' top 10 richest men list. The personal net worths of both Larry Page and Sergey Brin have since eclipsed that of Huateng again.
