RMS Caronia was a Cunard Line transatlantic steam ocean liner.

[1] John Brown & Company of Clydebank launched Caronia on 13 July 1904[2] and completed her in February 1905.

After returning to service, she sailed on a number of different routes, including: In 1931 Cunard laid up Caronia, and then sold her for £20,000 to Hughes Bolckow & Co for scrap.

In 1932 Hughes Bolckow sold her to Kobe Kaiun KK for £39,000, who renamed her Taiseiyo Maru ("The Atlantic Ship").

Kobe Kaiun had her towed to Osaka, where demolition work started on 28 March 1933.
