Earlston RFC play in blue hoops on white shirts, navy shorts and red socks.

The shirt sponsor of the club are locally based solicitor and estate agent company 'Cullen Kilshaw'.

No written records are available concerning the origins of the Club but it is believed that it was formed in the 1870s by two Yorkshiremen who were installing machinery in the local woollen mill.

In 1921 the present pitch at the Haugh (a Lowland Scots word meaning river meadow) was leased from A. Brownlie, Timber Merchants.

On 1 September 1923 the first Earlston 7-a-side Tournament was held and in 1935 the present cup, reputed to be one of the most valuable on the Border Sevens circuit, was purchased thanks to subscriptions from Club supporters.

Approximately one third of the pitch was dug out and concrete laid to make "hull-down" park for tanks (Polish Lancers) stationed in the area preparing for D-Day.
