Duke Kofi Appiah Danning (born 2 March 1991) is a Ghanaian-born Australian footballer who plays for National Premier Leagues club Belconnen United.

After playing for Canberra FC and then the O'Connor Knights in the ACT Premier League, Danning was invited to train with the Australian Institute of Sport (AIS) squad in 2007.

He impressed then coach Steve O'Connor and his successor Ray Junna enough to claim a full scholarship, and spent the following year with the AIS team.

[8][9][10] The following week, Kofi Danning made his starting debut against Queensland Roar at Suncorp Stadium, and scored his second senior goal in the 25th minute of the game.

Despite their opponents' home advantage, Sydney FC ran out deserving 2–0 winners, with Kofi Danning's strong work in the penalty area leading to Robbie Mileski's sealing goal in the 77th minute.

Danning tore the anterior cruciate ligament in his right knee during a match against Melbourne Victory in December 2009 and is expected to be out of action for up to nine months.

[23] In May 2015, Danning joined National Premier Leagues Victoria side Oakleigh Cannons FC on a free transfer.

[24] Born in Ghana but a resident of Australia since 1999, Danning had been caught up in FIFA's recent edict to tighten its international eligibility rules.

After almost a year of lobbying by the FFA on the basis that genuine immigrants should not be penalised, FIFA declared in August 2009 that Danning would be granted an exemption and cleared to play for the Young Socceroos[25] in the 2009 Under 20 World Cup in Egypt.
