Terry Cavanagh (/ˈkævənɑː/, KAV-ə-nah; born 1984) is an Irish video game designer based in London, England.

He has created over two dozen games, most notably VVVVVV, Super Hexagon, and Dicey Dungeons.

[1] After studying mathematics at Trinity College in Dublin, Cavanagh worked briefly as a market risk analyst before moving to focus on game development full-time in 2007.

While he received some attention in the press for his "serious and arty" indie games, Cavanagh faced significant financial difficulties in his early career.

[2] In the midst of the COVID-19 pandemic, in 2020, he gave away 1000 copies of three of his games for free in the hope it would "offer a distraction" to those in need of it.
