Roberto Tang Uy Jr.,[2] known as Pinpin Uy, is a Filipino politician from the province of Zamboanga del Norte, currently serving as Congressman in the House of Representatives of the Philippines representing the 1st legislative district of Zamboanga del Norte since November 13, 2023.

In 2013, Uy entered politics when he won as municipal mayor of Polanco, Zamboanga del Norte, and served for one term until his reelection defeat in 2016.

However, controversy arose as then COMELEC Chairman Saidamen Pangarungan was speculated to have told Zamboanga del Norte's Provincial Board of Canvassers to suspend Uy's proclamation due to a pending disqualification case for a supposed nuisance candidate named Federico "Kuya Jan" Jalosjos.

[8][9] On August 9, 2023, on a 12–2 vote, the Supreme Court ruled in favor of Uy more than a year after the COMELEC proclaimed the former the winning candidate in the May 2022 elections.

[10] On November 10, 2023, COMELEC declared Uy as the legitimate winner of the election; and three days later, was sworn into office as Zamboanga del Norte's 1st district representative.
