Prince William has been Colonel of the regiment since 2011. The prince's grandmother, Queen Elizabeth II, is Colonel-in-Chief of the Irish Guards, and the four other foot guards regiments.

The first regimental mascot for the Irish Guards was appointed in 1902 and they have all been named after Irish High Kings or legendary chieftains. Domnall ua Néill was High King of Ireland from 956 to 980.

The Irish Guards is the only Guards regiment permitted to have a mascot leading the battalion on all major parades.From a collection of 140 digital photographs relating to animals and the British Army, 2016. From a collection compiled by Cpl Tom Seaton-Norton, Royal Logistic Corps, 2017.
