Christine Loh Kung-wai, OBE, JP (born 1 February 1956), is Under Secretary for the Environment in Hong Kong.

She is a former Legislative Councillor, founder and CEO of Civic Exchange, founder of the Citizens Party, and founder of Hong Kong Human Rights Monitor.

Until her appointment as Undersecretary for the Environment, Loh was CEO of Civic Exchange, the Hong Kong think tank that she co-founded in 2000. She was named "Woman of the Year for 2006" by Hong Kong Business.[1] She has worked in many areas, including law, business, politics, media and the non-profit sector, but is best known as a leading voice in public policy in Hong Kong, particularly in promoting democracy and environmental protection. She has long been associated with the campaign to save Hong Kong's Harbour from excessive land reclamation and overdevelopment.

Loh received her Honourable degree on 15 July 2016 from University of Exeter for her contribution to environment protection. She said: "To be among the young graduates at Exeter makes me feel young and energetic again. It's like having a second chance to do better - to make up for not having done by best when I was a student. Perhaps like me when I was at my graduation many years ago, young people don't quite understand their capabilities and capacities yet. They will learn more about themselves in time and try hard to accomplish what they wish to do".

Loh was appointed to the Legislative Council (LegCo) in 1992. In 1995 and 1998 she ran in two direct elections and won by large margins. She co-founded, in 1995, the Society for Protection of the Harbour and was responsible for creating and sponsoring the historic Protection of the Harbour Ordinance. While part of the democratic camp in LegCo, she took a less confrontational approach than some, preferring to keep open lines of communication with the so-called pro-China camp.

In 2000, she and Lisa Hopkinson co-founded a Hong Kong-based non-profit think tank, Civic Exchange, and once again entered the political spotlight, but outside of the LegCo. She resigned as its chief executive on 11 September 2012 upon her appointment as Undersecretary for the Environment in the administration of CY Leung, taking up her new post the following day. At the same time, she resigned from all her positions in other non-profit organisations, academic affiliations, and non-executive directorships in commercial firms.
