Penang Free School

Penang Free School (PFS), located at Green Lane in George Town, Penang, Malaysia, is the oldest English-medium school in Southeast Asia. Founded in 1816, its academic achievements led to its inclusion in the Malaysian Ministry of Education's Cluster School and High Performance School systems.

This secondary school has been an all-boys school since its inception, although girls are now admitted for Form 6. In addition, the school has produced several notable Malaysian and Singaporean personalities, including Tunku Abdul Rahman, P. Ramlee, Wu Lien-teh, Lim Chong Eu, Tuanku Syed Putra, Tuanku Syed Sirajuddin and Wee Chong Jin; its alumni are known as the 'Old Frees'.

Penang Free School maintains its historical rivalry with St. Xavier's Institution, another school in George Town which also claims the honour of being Malaysia's oldest school.
