Kristian Arran Commons (born 30 August 1983) is a retired footballer, who played as an attacking midfielder.
Commons started his career at Stoke City and made his debut in 2000. After four years with the club he rejected a new contract and signed for Nottingham Forest on a free transfer. He made over 150 appearances for Forest in four years there, and helped them win promotion to the Championship in his final season. He then moved to Derby, again on a free transfer. Injury problems curtailed his goalscoring in his first two years there, but in his final season there he had scored 13 goals by the time of the mid-season transfer window.
In January 2011, Commons moved to Celtic for £300,000. He went on to win five Scottish League Championships, two Scottish Cups and one Scottish League Cup. He was the top goalscorer in Scotland in season 2013–14 with 32 goals, and that same season won both the PFA Scotland and Scottish Football Writers' Association Player of the Year awards. Commons fell out of favour at Celtic during 2016 and was briefly loaned to Hibernian. He was released by Celtic in May 2017 and subsequently retired.
