Kottawa (Sinhala: කොට්ටාව, Tamil: கொட்டாவை) is one of the main suburbs in Colombo, Sri Lanka and is administered by the Maharagama Urban Council.

[1] During the Sri Lankan Civil War, Kottawa's strategic location on one of the main roads connecting Panagoda Cantonment to Colombo made it a target for attacks.

[2] In June 2006, Major General Parami Kulatunga was killed by a suicide bomber just after passing Kottawa on his way to the Army Headquarters in Colombo from his residence in Panagoda.

[12] The northern end of the Southern Expressway is about 2 km (1.2 mi) east of Kottawa[14] on the High Level Road (A4) and the Outer Colombo Circular Highway also extends from here towards north.

An elevated track named "Neela" (Blue), 23 km (14 mi) in length, will connect Hunupitiya to Kottawa via Pelawatte.

[17][18] The Public-Private Partnership (PPP) project aims to address heavy traffic congestion during the morning and evening rush hours in Colombo.
