Regine Yau Wai-ching (Chinese: 游蕙禎; born 6 May 1991) is a former Hong Kong politician and former member of the localist camp Youngspiration.

Youngspiration fielded nine candidates in the 2015 District Council elections, in which Yau ran against legislator Priscilla Leung in Whampoa East.

[11] Representing Youngspiration in the 2016 Legislative Council election, she won the sixth and final seat in the Kowloon West geographical constituency.

[12] On 12 October 2016, Yau and her party colleague Baggio Leung attended the swearing-in ceremony at the first Legislative Council session.

The NPCSC insisted the oath taking must be conducted sincerely and accurately, and later stated that China would firmly oppose Hong Kong independence.

[17] Leung and Yau were found to have manifestly refused and wilfully omitted to take their oath – an act classed as declining and neglecting it.
