SS Creekirk was a cargo steamship that was built in Scotland in 1912 and sunk with all hands by a German submarine in 1940.

[1] In 1913 Mariston's owners sold her to Romania Prima Naţională de Navigație Maritimă,[5] who renamed her Milcovul and registered her in Brăila[2] on the River Danube.

In August 1916 Romania entered the First World War, and by the end of the year Milcovul had been requisitioned as a transport ship for the Imperial Russian Navy.

[1] In autumn 1940 Creekirk loaded 5,900 tons of iron ore at Wabana and Conception Bay in Newfoundland and then sailed to Sydney, Nova Scotia.

Creekirk had only one DEMS professional military gunner:[4] her armament would have been operated largely by members of her own Merchant Navy crew.
