Ananda Sastralaya (sinhala: ආනන්ද ශාස්ත්රාලය) is a public boys school located in Kotte, Sri Lanka. It was founded in 1890 as Kotte Buddhist English Mixed School. In 1952 a part of the school land was designated by the Government as an archaeological site since an ancient tunnel junction erected in the 16th century was found within the school premises.
