Auldearn (Scottish Gaelic: Allt Èireann) is a village situated east of the River Nairn, just outside Nairn in the Highland council area of Scotland. It takes its name from William the Lyon's castle of Eren (Old Eren), built there in the 12th century. 
Auldearn is an expanding area, with much development in the last 10 years. It has a small garden in the centre of the village called the Rose Gardens where people, old and young, gather. From Castle Hill, there is a view all around for miles.
Auldearn has one hotel, a small primary school and a Post Office shop.
Auldearn was the site of a battle in May 1645 (Battle of Auldearn), in which the MacLennans participated on the side of the Covenanters under their chief Ruaridh, as referred to in Sorley MacLean's poem "Heroes". The Royalists under Montrose won the day - with Clan Donald playing a major part in the battle, as is evidenced by the waulking song Clann Domhnuill an Cogadh Righ Tearlach I.
There was a Post Office repeater station on the outskirts of the village which was one of only two in the Highland area classed as being of "key importance to national defence" and a "most important link in the A.D.G.B.. It is incorrectly described as a radio station in the document and also now marked incorrectly as an "old telephone exchange". It is believed that it was a link from the RAF Sector Operations Centre at Raigmore.

Farming controversy 
In 2010 it was reported that meat from a bull grown from the embryo of a cow cloned in the US and reared on a local farm had entered the food chain. Newmeadow herd, based at Drumduan Farm, is the largest Holstein cattle herd in the Highlands.
