List of tartans

This is a list of tartans from around the world. The examples shown below are generally emblematic of a particular association. However, for each clan or family, there are often numerous other official or unofficial variations. There are also innumerable tartan designs that are not affiliated with any group, but were simply created for aesthetic reasons.
British noble and regimental tartans.
Tartans in this section are those of the current or former British royal family, of individual British nobility members, and of British military regiments that use traditional Scottish attire, mostly Highland regiments.
UK military or Government tartans.
A number of tartans, worn by UK military units, are known as Government tartans, and are defined in a Standard currently maintained by Defence Equipment and Support within the Ministry of Defence. They are known by a number, a name, or both. The commonest are Government 1, Black Watch; Government 1A, a slightly lighter form of Black Watch worn by the Royal Regiment of Scotland; and Royal Stewart.
The following list includes those Government tartans worn by UK military units as from the creation of the Royal Regiment of Scotland in 2006 onwards. Other units wear a named clan tartan without it being defined by this standard, e.g. 32nd (Scottish) Signal Regiment and the pipers of the Royal Corps of Signals wear Grant, and the tartan of 154 (Scottish) Regiment Royal Logistics Corps is MacDuff. For the Royal Regiment of Scotland, the pipes and drums in each battalion wear the uniform of their antecedent regiment (as listed below) for ceremonial purposes, but the Regiment's standard Government 1A for non-ceremonial purposes.
Note: 1 SCOTS Pipes and Drums were disbanded in 2021.
Scottish clan tartans.
The tartans in this list are those ascribed to particular clans of Scotland, including Highland, Lowland, Isles, and Borders clans. Their status varies widely; armigerous clans generally accept them, while some have been officially adopted or rejected by a clan chiefs. 
Scottish non-clan family tartans.
Tartans in this list are ascribed to specific families or surnames, though not to Scottish clans; they range in date from 21st century to considerably older.
Non-Scottish family tartans.
These are (mostly modern) tartans created for families without a direct connection to Scotland.
Organisational tartans.
Tartans in this list are modern ones pertaining to particular commercial, non-profit, and military organisations. 
Regional tartans.
Tartans in these lists were created (mostly in modern times) for particular national and sub-national jurisdictions, most often officially, though with some exceptions.
