Robert Dillon, 3rd Baron Clonbrock (29 March 1807 – 4 December 1893), was an Irish peer.
This was an Irish peerage and did not entitle him to an automatic seat in the House of Lords.
[citation needed] However, in 1838 he was elected an Irish representative peer.
Lord Clonbrock married the Honourable Caroline Elizabeth, daughter of Francis Spencer, 1st Baron Churchill, in 1830.
Lord Clonbrock remained a widower until his death in December 1893, aged 86.
