Jacqueline Wong Sum-wing (Chinese: 黃心穎, born 23 January 1989) is a Hong Kong actress, TV host and beauty pageant titleholder.

In 2012, Wong was attending the University of British Columbia, studying her Master of Business Administration before competing for Miss Hong Kong 2012.

On 16 April 2019, Wong received heavy media exposure for her physical intimacies with married Hong Kong singer and actor Andy Hui; dubbing it "安心".

At the time of the incident, Hui was married to singer-actress Sammi Cheng and Wong was in a steady relationship with actor Kenneth Ma.

She and Ma ended their relationship and Wong returned overseas to Los Angeles for 8 months to avoid public scrutiny and tabloids.

[11] During her hiatus, Wong’s scenes in the drama Forensic Heroes IV were re-shot with Roxanne Tong, who began dating Ma in 2020.

[14] After her 8-month hiatus, the dramas Finding Her Voice (牛下女高音) and Handmaiden United (丫鬟大聯盟), in which Wong played major roles, were aired to gauge the public's reaction; the series were met with low ratings.

[16] On Valentines Day (Tue, Feb 14, 2023), Jacqueline released a music video titled Crown Me (English song) with lyrics that addresses some of the criticisms she's received and her readiness to move on.
