The 38-year-old’s career lasted almost two decades, during which he played 109 times for Wales – a national record in his position – and was part of the side that reached the semi-finals of Euro 2016.
Hennessey made his professional club debut in 2006 for Wolverhampton Wanderers, playing on loan for clubs including Bristol City, Stockport County and Yeovil Town, before permanent moves to Crystal Palace, Burnley and his final club Nottingham Forest.
“I have decided to bring my playing career to an end, I look back with gratitude and forward with optimism as I take the next steps on my footballing journey,” Hennessey said on social media.
