The spouse of the Chief Executive of Hong Kong is the wife or husband of the Chief Executive of Hong Kong.
During British colonial rule, there were 27 spouses of the Governor of Hong Kong, 3 of which died in office. Matthew Nathan is the only Governor of Hong Kong that is not engaged. Since Hong Kong was handed back to China in 1997, there have been four women and one man that have occupied this role.
Informally called "First Lady", there is no official formal title for the spouse of Hong Kong's leader. They are however traditionally appointed by prominent non-governmental organisations in the city as their patrons or presidents, such as Red Cross, Community Chest, Scout Association, and Girl Guides Association.
When Carrie Lam became the first female to lead the city, there were calls to refer her husband Lam Siu-por to the "first gentleman", although Lam himself does not like the term and the Chief Executive said her husband should be called "the spouse of the chief executive". Lam also broke with tradition of taking up honorary roles in community groups.
