Mullaitivu fort (Sinhalese: මුලතිවු බලකොටුව; Tamil: முல்லைத்தீவுக் கோட்டை) was built by the Dutch in Mullaitivu, Sri Lanka. The original fort, a small wooden structure with palisades and earth, was erected in 1715. In 1721 the Dutch constructed a quadrangular fort on the site. The fort was initially erected to control the unauthorised commerce between the Chetties and the Kingdom of Kandy, it subsequently formed part of a strategic defence of Dutch territory against the Vannimai. No visible evidence of the fort remains.
