Estline (sometimes spelled EstLine) was a Swedish-Estonian shipping company, owned jointly by Nordström & Thulin and the Estonian Government via Estonian Shipping Company (ESCO). Estline was founded in 1990 and had a 10 year exclusive right to the passenger traffic between Stockholm, Sweden and Tallinn, Estonia. In 1998, Nordström & Thulin left the joint venture, making Estline a fully owned Estonian shipping company. By the end of 2000, Estline´s ships were chartered by Tallink.
