Badulla (Sinhala: බදුල්ල, Tamil: பதுளை) is the capital and the largest city of Uva Province situated in the central hills of Sri Lanka.

Badulla is located in the southeast of Kandy, almost encircled by the Badulu Oya River, about 680 m (2,230 ft) above sea level and is surrounded by tea plantations.

The city was the terminus of upcountry railway line built by the British in order to take mainly tea plantation products to Colombo.

Badulla has a wet season from October to January, and has cooler temperatures in December to February compared to the rest of the year.

Badulla was an isolated village until the British built roads from Kandy and Nuwara Eliya in the mid 19th century, as part of the growing plantation economy.
