Khulna was part of the ancient kingdoms of Vanga or Samatata. In the 12th century, it came under the Sena dynasty during the reign of Ballal Sena and formed part of the Bagri division of Bengal. The previous name of this region was Jalalabad.

During the 14th century, Shamsuddin Firoz Shah became the first Muslim ruler to arrive in the city. The Muslim settlements in the city increased during the time of Shamsuddin Ilyas Shah. Subsequently, many mosques and shrines began to be established. In the 15th century, a Muslim saint named Khan Jahan Ali acquired a jagir (fiefdom) comprising a large part of the greater Khulna Division from the king of Gauḍa. Later he started to exercise full rights of sovereignty and continued to do so till his death in 1459.

After the death of Khan Jahan Ali, the city again became a part of the Sultanate of Bengal. During the reign of Daud Khan Karrani in the 16th century, Vikramaditya, one of the chief ministers of the ruler, obtained a grant in the southern Bengal including Khulna when the ruler was busy fighting the Mughals. He then established a sovereign kingdom, having the capital at Iswaripur currently in Jessore District. Vikramaditya was succeeded by his son Pratapaditya who gained preeminence over the Baro-Bhuyans, holding strong possession of Southern Bengal. He was eventually defeated by Man Singh I, a Hindu general of the Mughal emperor Akbar, in 1611 AD.

Khulna remained under the rule of autonomous nawabs (rulers) of Bengal till 1793, when the British East India Company abolished Nizamat (local rule) and took control of the city. In 1842, the city became a part of Khulna subdivision of Jessore District. In 1882, it became the headquarters of Khulna District, comprising the then Khulna and Bagerhat subdivisions of Jessore district, Satkhira subdivision of 24 Parganas district and the Sundarbans.

Khulna was declared as a Pouroshava / Municipal council in 1884 and promoted to a Municipal corporation in 1984 on the platinum jubilee of Khulna Pouroshava.

In 1990 Khulna has been declared as a City Corporation.
