Steven Kwok Wing-kin (Chinese: 郭永健; born 30 November 1986) is a Hong Kong politician and the chairman of the Labour Party since 2017.

He ran in the "Five Constituencies Referendum" launched by the pan-democrats under the banner of "Tertiary 2012" in 2010.

[1] He joined the pro-democracy primary for the 2018 New Territories East by-election, competing against Tommy Cheung and Gary Fan for the seat left vacant by Baggio Leung who was disqualified over the oath-taking controversy.

Kwok was arrested on 1 November 2020, along with six other democrats, in connection with the melee that had broken out in the LegCo on 8 May 2020.

On that day, Starry Lee, the incumbent chair of the House Committee of the Legislative Council, had attempted to commence a meeting of the Committee after extended stalling tactics of the pan-democratic camp over the previous months.
