SS Reina Victoria-Eugenia was a steam ocean liner and mail ship launched in 1912 in England and operated by the Compañía Transatlántica Española (CTE).

Swan, Hunter & Wigham Richardson built Reina Victoria-Eugenia at its Neptune Yard in Low Walker, England, launching her on 26 September 1912 and completing her in February 1913.

[1] At the same time William Denny and Brothers built her sister ship Infanta Isabel de Borbon,[2] and there were significant technical differences between the two.

CTE ordered a similar combination of triple-expansion engines and low-pressure turbine for Infanta Isabel de Borbon and Reina Victoria-Eugenia.

[3] In 1910–11 Chantiers de l'Atlantique had put this idea into practice when it built the liner Rochambeau for Compagnie Générale Transatlantique.

Reina Victoria-Eugenia had a taller funnel, whereas Infanta Isabel de Borbon had cowl tops on her king-posts.

Her public saloons were decorated in various historicist styles including Louis XVI, Neo-Georgian and Jacobean Revival.

It was reported that once the ship reached Spain, she achieved higher speeds in deeper water and better weather off Cádiz.

On 12 March 1913 Reina Victoria-Eugenia started her maiden voyage from Barcelona via Malaga, Cádiz, Tenerife and Montevideo to Buenos Aires.

[10] In the First World War both Infanta Isabel de Borbon and Reina Victoria-Eugenia seem to have made some trips to New York.

[10] During the First World War the Entente Allies did not allow neutral ships to carry men of military age who were citizens of the Axis powers.

In May 1918 Reina Victoria-Eugenia was en route from Tenerife to Spain when the Royal Navy forced her to divert to Gibraltar for examination because the British Admiralty had been alerted that there were German men of military age among her passengers.

Authorities in Gibraltar found a German sailor from the auxiliary cruiser Kaiser Wilhelm der Grosse who had been interned on the Canary Islands since his ship was sunk in August 1914, and who was travelling under Spanish armed escort.
