Royal Marine is a bay horse with a narrow white stripe bred and owned by Sheikh Mohammed's Godolphin organisation.

He was sired by Raven's Pass who showed top class form in Europe but is best known for being the only horse trained in Britain to win the Breeders' Cup Classic.

[4][5] Royal Marine made his debut in a minor race over six furlongs at Newmarket Racecourse on 25 August in which he was ridden by Pat Cosgrave and started the 9/4 second favourite in an eleven-runner field.

[7] On 7 October Royal Marine was sent to France and moved up sharply in class to contest the Group 1 Prix Jean-Luc Lagardère over 1600 metres at Longchamp Racecourse.

[9] In the winter of 2018/19 Royal Marine was sent to Godolphin's base in the United Arab Emirates and made his three-year-old debut when finishing fourth in the UAE 2000 Guineas Trial at Meydan Racecourse on 10 January.

Ridden as on his previous start by Christophe Soumillon he pulled hard in the early stages before coming home fourth of the eight runners behind Skardu.
