Operation Albion was the German land and naval operation in September–October 1917 to invade and occupy the West Estonian Archipelago, then part of the Autonomous Governorate of Estonia, Russian Republic. The land campaign opened with landings at the Tagalaht, Saaremaa on 11 October 1917, after extensive naval activity to clear mines and subdue coastal artillery batteries. The Germans secured the island by 16 October. The Russian Army evacuated Muhu on 18 October.

After two failed attempts, the Germans managed to land on Hiiumaa on the 19th and captured the island on the following day. The Russian Baltic Fleet had to withdraw from the Suur Strait after major losses (see Battle of Moon Sound). The Germans claimed 20,000 prisoners and 100 guns captured during the Operation Albion from 12 October.

At the beginning of World War I the islands were of little importance to either Imperial Russia or Germany. However, after the revolutionary turmoil in Russia during 1917, the German high command believed capturing the islands would outflank Russian defences and lay St. Petersburg vulnerable to attack.
