Jonny Hayes (born 9 July 1987) is an Irish professional footballer who plays as a winger for the Scottish Premiership team Aberdeen and Republic of Ireland.
He began his career in England with Reading, but did not break through to their first team, serving two loan spells prior to being released. Picked up by Leicester City, his opportunities were also limited and again he went out on loan twice. He joined Inverness Caledonian Thistle in Scotland in 2009, becoming an important member of the team, a status he also enjoyed after moving on to Aberdeen three years later. In 2017 he signed for Celtic, the reigning Scottish champions, helping them to defend their title and win the following two as a squad member, sometimes playing at left back; he left in 2020 and returned to Aberdeen in June 2020
