Gregory Yong Sooi Ngean (20 May 1925 – 28 June 2008) was a Singaporean Catholic prelate who served as Archbishop of Singapore from 1977 to 2000.
In 1953, Yong left for studies in Rome where he was conferred a Doctorate in Canon Law,[2] the very first local priest to achieve the distinction.
On 3 February 1977, Yong was appointed to succeed Archbishop Michel Olçomendy as the first of the local clergy to lead the Church in Singapore.
In August 1992, Yong served on the first Presidential Council for Religious Harmony as a representative of the Roman Catholics in Singapore.
[4] Yong's last public appearance was in May 2004, when he was summoned as a prosecution witness in the trial of Catholic priest Joachim Kang, who was convicted and jailed for misappropriation of S$5.1 million in church funds.
