Adelino Sitoy (6 February 1936 – 15 April 2021) was a Filipino politician, lawyer, and Cebuano language advocate from Cebu, Philippines. He served as the Presidential Legislative Liaison Office (PLLO) Secretary under the administration of Rodrigo Duterte from September 2016 until his demise. He was the elected vice mayor of Cordova, a position from which he resigned at the time of his appointment at PLLO. The Duterte administration in tribute upon his death praised him for facilitating the passage of laws, but some lawmakers allegedly blamed his office for failing to provide timely coordination in forwarding a few pieces of legislation such as the bill for security of tenure (anti-endo) and coconut farmer trust fund, a bill which was vetoed and then later signed into law by Duterte.
