Ayr United were formed in 1910 with the amalgamation of Scottish League sides Ayr Parkhouse and Ayr FC, who in turn had been formed by previous club mergers and began playing their home matches at Somerset Park, Ayr from the 1910/11 season. 

Until 1994, when the Scottish League admitted an Inverness side to the league, Ayr United were the only Scottish League side to be formed as the result of a merger. 

However, as the Inverness sides were an amalgamation of two non-league sides, Ayr United still remains as the only side to be the product of a merger of two former league sides.

Ayr United have the nickname 'The Honest Men' taken from the poetry of Scotland's National Bard, Robert Burns, who came from Alloway, near Ayr.  He wrote about

'Auld Ayr, wham ne'er a toon surpasses, for honest men and bonnie lasses'.

So with his poetry Ayr United’s nickname of ‘The Honest Men’ was born.

Club Records

Ground capacity - 12,128.

Highest Attendance - The highest attendance at Somerset Park was recorded on 13th September 1969 when Rangers came visiting.

The crowd swelled to a massive 25,225 as young children and adults alike were forced to stand within the boundary wall around the ground.  Ayr United won the match 2-1.

Such a crowd could never fit into Somerset Park again since the regulations changed which has reduced the ground capacity.
