Sanskrit Collegiate School is one of the oldest schools in Kolkata, India, teaching grades from class 1 to 12 under the West Bengal Board of Secondary Education and the West Bengal Council of Higher Secondary Education.

It was established during the Governor-Generalship of Lord Amherst, based on a recommendation by HT James Prinsep and Thomas Babington Macaulay among others.

The institution rose to prominence during the principalship by Ishwar Chandra Vidyasagar in 1851, who admitted students from other than the Brahmin caste.

The school was once combined with Sanskrit College and was situated in the same building which was built in a Victorian Architecture.

Intra-section competitions as well as inter-section and inter-class ones ensure that almost every student gets a chance to play at the official tournament.

The students engage in sports (mostly football with some playing cricket) during the recess (commonly called the tiffin period) which lasts for 20 minutes from Monday to Friday.

The annual prize distribution ceremony sees plays, vocational and instrumental music performed by the students as well as other cultural programs held at the Derozio Hall.
