Maliyadeva College (Sinhala: මලියදේව විද්‍යාලය) is a national school controlled by the Sri Lankan central government.

It is located in Kurunegala, Sri Lanka, and was established in 1888 by the Buddhist Theosophical Society, led by Colonel Henry Steel Olcott.

][citation needed] The term "Devans" is used to refer to the former and present pupils of Maliyadeva College.

In June 1888, a new school with one student was opened at a place in Bodhiraja Mawatha near the present Central Bus Stand in Kurunegala, by Seminaries A. Bamunu-Arachchige.

He was a young Maha-Vidane (Vidane Arachchi) who had been put in charge of four villages by Maha-Mudaliyar Bandaranaike and Colonel Henry Steel Olcott.

In 1909, the school moved to new premises at a Buddhist Temple, Ethkanda Viharaya, along the Kandy—Kurunegala main road.

Semenaries retired from governing the school in 1931 and, after forty-three years as Maha-Vidane, he gave the position to Bandaranaike's son, the future prime minister of Ceylon.

In 1934, a batch of students from Maliyadeva College appeared for the SSC Examination (equivalent to current GCE) for the first time.

Former governor Maha-Vidane Semenaries and Mudaliyar Bandaranaike, who was on his last term, gave the order for the school to be moved to its current location along the Negombo - Kurunegala road.

Only the boys were moved back, and the Maliyadeva Girls' College began functioning as a separate school.

University Entrance (Arts) and SSC (equivalent to current GCE) Science classes began and D. B. Dissanayaka was appointed as the vice-principal during this year.

Maliyadeva had won the all-island awards in oriental music and orchestra competitions for many years consecutively.

1979 saw the end of an era when D. B. Dissanayake retired after serving the school for fourteen years as the principal.

Facilities include playgrounds, an auditorium, a swimming pool, a basketball court, an Indoor stadium, children's parks, computer labs, medical and dental centres, a two-storied shrine for Buddhist monks, a gymnasium, a library, a botanical, zoological, physical and chemical labs, hostel, canteens, co-operative shops, milk bar and transport services.

The four houses compete in the annual inter-house sports meeting which is usually held in the first term of the academic year.

The match is traditionally held at the Welagedara Stadium in Kurunegala and played over two days, with the winning team awarded a trophy.
