Pengiran Anak Muhammad Yasin bin Pengiran Tua Omar Ali (died 1951) was a Bruneian nobleman who held the position of Pengiran Pemancha in Brunei. Serving from 1914 until 1950, and later becoming the Pengiran Bendahara from 1950 to 1951, these titles marked him as the third and first most senior rank within the wazir class of state officials respectively. He has served under the reign of Sultan Muhammad Jamalul Alam II, Ahmad Tajuddin and Omar Ali Saifuddien III.

He served as joint regent of Brunei alongside Pengiran Bendahara Pengiran Anak Abdul Rahman during Ahmad Tajuddin's minority from 11 September 1924 to 19 September 1931. The two were referred to as "the two wicked uncles" and were alleged to have exerted a negative influence on the young sultan. Accusations include impeding his overseas education, arranging a concubine for him at thirteen, and fostering such an atmosphere of fear that he cooked his own meals in soda water to avoid poisoning.
