Patrick Walsh (died 1578) was an Irish prelate who served as the Bishop of Waterford and Lismore from 1551 to 1578.

[1] Four years later, Walsh was nominated the Bishop of Waterford and Lismore by Edward VI of England on 9 June 1551[2][3] and was consecrated by royal mandate on 23 October 1551.

[5][6] But following the accession of Queen Elizabeth I, Walsh supported the crown's reformation legislation in the 1560 Irish Parliament.

In a letter of 12 October 1561, the papal legate Fr David Wolfe SJ described all the bishops in Munster as 'adherents of the Queen'.
