Teresa Cheng Yeuk-wah GBM GBS SC JP (Chinese: 鄭若驊; born 11 November 1958) is a Hong Kong Senior Counsel, arbitrator and politician.

Cheng co-authored numerous books and articles, including Construction Law and Practice in Hong Kong and Arbitration in Hong Kong: A Practical Guide, published by Sweet & Maxwell, and papers in the International Council for Commercial Arbitration Congress Series, published by Kluwer Law International.

She is the current chairperson of the Financial Dispute Resolution Centre and Air Transport Licensing Authority and a member of the Construction Industry Council and two Working Groups on Mediation in Hong Kong.

[2] On 5 January 2018, Chief executive Carrie Lam announced her appointment as the Secretary for Justice with effect from the following day, succeeding the retiring Rimsky Yuen.

[4] Ming Pao and Apple Daily revealed on 5 January 2018, just before Cheng was due to take office, that there was an extra staircase seemingly leading to illegal structures in her residence at No.

[7] Further reports, confirmed by Buildings Department inspectors, revealed that there were ten unauthorised extensions, including the basements and the rooftop structures, on Cheng's residence and an adjacent property belonging to her husband, Otto Poon Lok-to.

[10] Many critics, including former Director of Public Prosecutions Grenville Cross, said he found it "very surprising" that no independent legal advice was sought on Leung's case and urged the Secretary for Justice to explain.

[14] Following the death of Chow Tsz-lok, Cheng was heckled and jostled by supporters of the protests in London, who called her "murderer", when she was entering Bloomsbury Square to give a lecture.

[16] Earlier in November 2020, Cheng claimed that the national security law had encouraged positive investment and commerce in Hong Kong.

"[18] On 3 July 2020, the Chinese official media, Xinhua News Agency, stated that the Committee for Safeguarding National Security of the Hong Kong Special Administrative Region was formally established.

[19] In August 2020, Cheng and ten other officials were sanctioned by the United States Department of the Treasury under Executive Order 13936 by President Trump for undermining Hong Kong's autonomy.

[20][21][22] Analogue Holdings Limited (ATAL; 1977) a company controlled by Poon Lok-To, spouse of Cheng, announced on 11 August that it has sold back 2% of shares of Transel Elevator & Electric Inc. (TEI) at cost to Mark Gregorio, chairman of TEI, for US$1.4 million (approximately HK$10.92 million) to reduce ATAL's interest from 51% to 49% after the sanction against Teresa Cheng.

[28] The Hong Kong Bar Association also made a similar request, saying that Cheng must "take appropriate action and come forward to staunchly defend the independence of the judiciary.

[30] In February 2021, Cheng claimed that some news media were using "biased expressions that fail to reflect the facts in an objective manner" when it came to describing appeals or sentencing reviews made by the Department of Justice.

[31] In the first trial under the national security law, against Tong Ying-kit, Cheng in early February 2021 told the defendants that the case would not be determined by a jury, but rather three judges.

[35] As part of the initiative, Cheng in November 2020 said that a pilot program would be started to teach primary and secondary schoolchildren about "rule of law values" and prevent children from having "incorrect concepts" about topics such as the 2019–20 Hong Kong protests.
