Marjorie Yang Mun-tak GBS (Chinese: 楊敏德; born 1952) is Chairwoman of Esquel Group, a Hong Kong–based textile and apparel manufacturer with operations throughout the world, producing over 110 million cotton shirts every year for well-acclaimed brands and retailers such as Ralph Lauren, Tommy Hilfiger, Hugo Boss, Nike, and Marks and Spencer.

[1] In 2017, Yang financially backed former finance minister and colleague John Tsang for the position of Chief Executive of Hong Kong, though he eventually lost to Carrie Lam.

The Esquel Group has provided microfinance to 300 rural households in China's unrest-ridden Xinjiang region, where the privately held company has cotton farming, ginning and spinning operations.

The Foundation is geared mostly towards improving the standards of teaching, encouraging education and learning, and enhancing health and public hygiene for Uyghur minority students in areas outside the regional capital, Ürümqi.

In 2018, Yang announced the launch of 'Integral', an initiative aimed to encourage business leaders and academics to develop a balanced and less environment-damaging growth model for China.
