Katrina Leung (simplified Chinese: 陈文英; traditional Chinese: 陳文英; pinyin: Chén Wényīng; born 1954) is a former high value Federal Bureau of Investigation (FBI) informant and Ministry of State Security (MSS) agent who, on April 9, 2003, was indicted by the United States Department of Justice for "Unauthorized copying of national defense information with intent to injure or benefit a foreign nation". Her case was later dismissed on January 6, 2005, because of prosecutorial misconduct, but an appeal by the U.S. Attorney resulted in a plea bargain of guilty to lesser charges on December 16, 2005. She was alleged by the United States government to have contaminated twenty years of intelligence relating to the People's Republic of China, as well as critically compromising the FBI's Chinese counterintelligence program. She was known by a variety of aliases, including Chan Man Ying, Chen Wen Ying, Luo Zhongshan, and Parlor Maid.
