Jalandhar (Punjabi Gurmukhi: ਜਲੰਧਰ), formerly Jullundur, is a city in the Doaba region of northwestern India state of Punjab. Jalandhar is the oldest city in Punjab and has seen rapid urbanisation, developing into a highly industrialised centre of commercial activity.

Jalandhar was the capital of Punjab from India’s independence until Chandigarh was built in 1953. According to history, the city is named after the Daitya king Jalandhara who according to the Padma became so powerful by virtue of his austerities as to be invincible. Jalandhar has recently been selected in the third list of 27 Smart Cities and is set to be the first sports city of the country.
