Patrick Byrne (1783 – 10 January 1864) was an Irish architect who built many Catholic churches in Dublin.

As Baker had been a student and partner of James Gandon, Byrne would likely have been introduced to neoclassicism around this time.

He suggests that if Byrne did not have his own firm, then he "...was almost certainly working as a partner or chief assistant with another architect"; likely his teacher, Henry Aaron Baker, or Francis Johnston.

A member of the Society of Irish Artists from 1845 to 1849 and an architect to the Trustees of the Royal Exchange between 1847 and 1851.

[1] The parish priest of the Rathmines Church, William Meagher gave a eulogy of Byrne, “Of this gifted man whose talents and disinterested care have laid us under such obligations, of him who designed the portico of St Paul's and erected the majestic shrine of St Audoen's and the solemn cathedral-like pile of St James and the bold and beauteous dome of Our Lady of Refuge, of the accomplished and good and generous Patrick Byrne how truly may it not be said that he regarded the beauties of classical and mediaeval art with equal reverence, studied their several excellencies with equal assiduity & wrought upon the principles of both with equally supereminent success.”[5] A selection of works by Patrick Byrne in chronological order.
