The Queen's Own Highlanders (Seaforth and Camerons), officially abbreviated "QO HLDRS," was an infantry regiment of the British Army, part of the Scottish Division. It was in existence from 1961 to 1994.

The Seaforth Highlanders was a line infantry regiment of the British Army, mainly associated with large areas of the northern Highlands of Scotland. The regiment existed from 1881 to 1961, and saw service in World War I and World War II, along with many smaller conflicts. In 1961 the regiment was amalgamated with the Queen's Own Cameron Highlanders to form the Queen's Own Highlanders, which merged, in 1994, with the Gordon Highlanders to form the Highlanders. This later joined the Royal Scots Borderers, the Black Watch, the Royal Highland Fusiliers and the Argyll and Sutherland Highlanders to create the present Royal Regiment of Scotland.
