Patrick Heron of Kirroughtree (1736–1803) was a Scottish banker and politician. From 1794 to 1803 he was a Whig member of Parliament for Kirkcudbright Stewartry.
He married Jean Home, in 1761, daughter of Henry Home, Lord Kames, but the couple were divorced in 1772. In 1775, he married Elizabeth Cochrane, cousin to the diarist James Boswell.
He was a founder of a bank in Ayr, Douglas, Heron & Company, which went bankrupt in 1773.
Heron defeated the incumbent, John Gordon, in 1794, and was elected again in 1803, defeating Tory candidate, Montgomery Stewart. However, he was unseated subsequently by decision of a Committee of the House of Commons. The campaigns are recorded in three works by Robert Burns, now known as the Heron Ballads. Burns was himself a supporter of Heron:
An' there will be trusty Kerroughtree,
If the virtues were pack'd in a parcel,
- Whose honour was ever his law,
- His worth might be sample for a'.
