Seberang Perai is a city in the Malaysian state of Penang. Located on the Malay Peninsula and separated from Penang Island by the Penang Strait, it shares borders with Kedah to the north and east and Perak to the south. The city spans an area of 748 km (289 sq mi) and had a population of 946,092 as of 2020, making it the third largest city in Malaysia.
Originally a part of Kedah, the territory containing the city was ceded to the British East India Company in 1800. It was named Province Wellesley and has been administered as part of Penang ever since. The territory became a centre for cash crop agriculture, while the development of new towns such as Butterworth and Bukit Mertajam followed with the advent of roads and railways towards the end of the 19th century.
