SS Calgaric was a steam ocean liner that was completed in 1917, assumed service in 1918 and scrapped in 1934. She was built for the Pacific SN Co Line as Orca. In 1923 she was transferred to the Royal Mail Line. In 1927 she was transferred to White Star Line and renamed Calgaric.
Orca was the third of three sister ships built for Pacific Steam. The first was SS Orduña, launched in 1913, and the second was SS Orbita, launched in 1914.

Harland & Wolff built Orca at Belfast during the First World War. She was yard number 442, built on slipway number 7. She was launched on 5 April 1917 and delivered to Pacific Steam on 25 May 1918.[2]
