Saaremaa Shipping Company was a company which served the main sea routes between the Estonian mainland and its two major islands, Saaremaa and Hiiumaa. Since 1 October 2016 these routes have been operated by TS Laevad. SLK was declared bankrupt in November 2018. SLK's three sister ships "Saaremaa", "Hiiumaa" and "Muhumaa" were sold to Elb-Link in Germany. They were sold again in 2018 to service routes in eastern Canada.
