Petrus Vuyst or Vuijst (1691, Alkmaar, Netherlands – 19 May 1732, Batavia) was the 20th Governor of Ceylon during the Dutch colonial period.

[2] The couple lived in Leiden where they had one surviving daughter, before leaving for the East Indies on 16 May 1716 on the ship De herstelde Leeuw.

[1] Vuyst's rule in Ceylon began well, as he ordered the fortifications of the strategic port of Galle to be strengthened, and had a new road built from the Fort of Colombo to the suburb of Mutwal.

At his instigation a number of people, including Dutch settlers and officials, were sentenced to death on false or trumped up charges.

He was dismissed from his position in 1729 and summoned to appear before the High Council in Batavia, which found him guilty of "judicial murders" and other serious crimes.
