A bawn is the defensive wall surrounding an Irish tower house. It is the anglicised version of the Irish word bábhún (sometimes spelt badhún), possibly meaning "cattle-stronghold" or "cattle-enclosure".See alternative traditional spellings under badhbhdhún in Foclóir Uí Dhuinnín: http://www.scriobh.ie/Page.aspx?id=26&l=1 {{Webarchive|url=https://web.archive.org/web/20200412184957/http://scriobh.ie/page.aspx?id=26&l=1 |date=12 April 2020 }}. The standard modern spelling is bábhún: Ó Domhnaill, Niall (eag.), Foclóir Gaeilge Béarla, Baile Átha Cliath: Oifig an tSoláthair (1977), p. 73. The Irish word for "cow" is bó and its plural is ba. The Irish word for "stronghold, enclosure" is dún, whose genitive case is dúin.

The original purpose of bawns was to protect cattle from attack. They included trenches that were often strengthened with stakes or hedges. Over time, these were gradually replaced by walls. The name then began to be used for the walls that were built around tower houses.

English and Scottish names for the same thing include "pele" (hence pele tower) and "barmkin".
