The Toledo City Science High School (Filipino: Mataas na Paaralang Pang-Agham ng Toledo), also known as TCSHS, is a public science high school in Ilihan Heights, Toledo, Cebu, Philippines.

It was founded in 1996 in response to the department's call to focus in math and science education.

The school is in Barangay Ilihan which got its name from the word "Alihan" whose meaning is to barricade.

During World War II, Filipino guerrillas had foxholes in this barangay to prevent the Japanese from attacking Toledo City.

The area is an ideal place to hide the natives from the Japanese invaders.
