Thalawathugoda (, ) is a vicinity of Maharagama governed by the Urban Council of Maharagama. It is located approximately from the centre of Colombo, adjacent to Battaramulla and Pelawatte on the Borella-Kottawa Road, bordering Sri Jayawardenapura-Kotte. The Diyawanna Oya (Parliament Lake) forms the "Sri Jayawardenapura-Kotte" boundary of Thalawathugoda.
Thalawathugoda is served by the Maharagama Urban Council.
Earlier, Thalawathugoda had a sub post office which was controlled by the Battaramulla main post office. The promoted Thalawathugoda Post Office was opened recently. However, a few areas fall under the Hokandara and Pannipitiya postal limits.
