Marcelino "Nonoy" Chicano Libanan (born September 20, 1963) is a Filipino lawyer and politician who has served as the House minority leader since 2022. A sectoral representative for 4Ps Partylist, he has been a member of the chamber since 2022 and previously served as the representative for Eastern Samar's lone district from 1998 to 2007.

Libanan entered politics in 1992 after being elected as the vice governor of Eastern Samar, a position he would hold until 1995. He was first elected to Congress in 1998, under Lakas. As a representative, he pursued legislation urging the repatriation of the Balangiga bells to Eastern Samar and was involved in drafting the Human Security Act. He left the chamber early in 2007 to become the commissioner of the Bureau of Immigration, a position he would hold until 2010. After leaving office, he was implicated in the Pork barrel scam.

Libanan returned to electoral politics in 2022, after being elected as the sectoral representative for 4Ps Partylist. In July 2025, he was elected House minority leader. During his tenure, he pursued legislation related to health and education. During the impeachment of Sara Duterte, Libanan was named as the lead prosecutor for the trial.
