MS Galaxy 1 is a cruise ferry built in 2006 by Aker Finnyards, Rauma, Finland and was at the time the largest ship delivered to ferry operator Tallink. Between 2006–2008 she held the distinction of being the largest ship ever to be registered in Estonia; a title later held by her replacement the sister ship MS Baltic Princess.
Between July 2008 and September 2022, Galaxy sailed on the Stockholm–Åland–Turku route under Tallink's Silja Line brand. After ending this service, the Galaxy is scheduled to be used as refugee housing in the Netherlands for at least seven months.
