HMS Bristol was a Town-class light cruiser built for the Royal Navy in the first decade of the 20th century. She was the lead ship of the five in her sub-class and was completed in late 1910. The ship spent part of her early career in reserve before she was transferred to the 4th Cruiser Squadron of the North America and West Indies Station in mid-1914. Bristol was briefly deployed to Mexico during the Mexican Revolution to protect British interests there.

The Town class was a group of twenty-one light cruisers built for the Royal Navy (RN) and Royal Australian Navy (RAN) of the first half of the 20th Century. These vessels were long-range cruisers, suitable for patrolling the vast expanse covered by the British Empire. These ships, initially rated as second class cruisers, were built to a series of designs, known as the Bristol, Weymouth, Chatham, Birmingham and Birkenhead classes – all having the names of British towns except for the RAN ships, which were named after Australian cities.
