The Leesiders have bolstered their front line with the signing of the Youths attacker after he topped the First Division goalscoring charts
Speaking to corkcityfc.net, the Furlong revealed his delight at signing for the Turners Cross club and said that he was 'very impressed' by the support that the club enjoyed.
He said: "I’m delighted to have signed for the club and am really looking forward to this next stage of my career. I spoke with Tommy during the week and was very impressed at what he had to say.
"Having played against Cork City in the First Division in 2010 and 2011, I was very impressed with the support and the atmosphere, and that was an important factor for me.
Cork manager Tommy Dunne said that he was 'very pleased' with the signing, which is the club's second in the space of a week after the signing of Daryl Kavanagh from Shamrock Rovers.
"I am very pleased that Danny has signed for the club," Dunne told the club's official website. "It is another addition in the attacking area of the squad, which will increase the competition for places within the squad.
"Danny has done very well in the First Division over the last couple of years, scoring goals on a regular basis, so we are hoping that he can now settle into the Premier Division and continue that good form," he said.
Furlong was the top goalscorer in the First Division last season, scoring 13 goals in 24 appearances for Wexford Youths.
