Ooi Chuan Aun[1] (simplified Chinese: 黄泉安; traditional Chinese: 黃泉安; pinyin: Huáng Quán Ān; Jyutping: Wong4 Cyun4 On1; Pe̍h-ōe-jī: Ûiⁿ Choân-an; born 2 November 1955[2]), better known as Jeff Ooi, is a Malaysian IT consultant, blogger, photographer and politician who served as the Member of Parliament (MP) for Jelutong for two terms from March 2008 to May 2018.

Jeff Ooi used to write a blog known as "Screenshots...", which he started on 2 January 2003, covering current issues relating to Malaysia, mainly on politics.

[7] Ooi stood as a DAP candidate in the 2008 general election for a seat in Jelutong, Penang,[8][9] which he won by 16,246 votes.

[14] The Malaysian court ordered Ooi to remove more than 10 posts on his blog that the NSTP claimed were libellous by 17 January.

[15] Prime Minister Abdullah Ahmad Badawi defended the legal action launched against Ooi, saying the Internet was not exempt from defamation laws.

In early August 2009, Ooi had labelled Mohd Razali Abdullah, a Penang Island Municipal Council (MPPP) councillor, an Islamic extremist.

[19] In November 2013, Ooi had drawn flak by calling 'kucing kurap' (literally mangy cats) two MPPP officers accompanying him as Jelutong MP during his visit to an illegal hawker site when he was unsatisfied with them who were ill-informed.
