St. Anthony's National Secondary School (Malay: Sekolah Menengah Kebangsaan St. Anthony) is a public secondary school in Sarikei, a town in the East Malaysian state of Sarawak.

[citation needed] The roots of St Anthony's School can be traced back to 1932 when Bishop John Baus started the school in one wooden shack on the side of Repok Road where the current priest's abode and the old St. Anthony's Church are.

Rev Father C. Quadekker secured the land across Repok Road in 1935 and built a block with 4 classrooms at the present location of St Anthony's School.

Father Quadekker was considered by some as the founder of St Anthony's School.

During World War II from 1941-1945, the school was used by the Japanese as a camp for hundreds of its soldiers.

In 1956, the school was managed by Rev Priest J Hol and Mc Hugh.

The first group of Form 3 students sat for SRP (Sijil Rendah Pelajaran / Lower Education Certificate) in 1956.

KA Titus was the last foreigner who headed St Anthony's School from 1972-1980.

Other facilities like basketball court, bicycle shed, car porch for staff, extension of toilets and school fence were built.

SAS had won many awards at divisional, state and national levels.

With the support of parents, the students and ex-Anthonians, the school can look forward to continue to excel.
