The 22-year-old Brazilian joined the Magpies on loan from Chelsea in January and made a huge impact in the second half of the campaign as Rafa Benítez's side climbed away from the bottom three to finish tenth in the Premier League.
He made 13 appearances - all from the start - and scored twice, with both goals coming in a vital 3-0 win against Southampton in March.
Kenedy is now back at Stamford Bridge as the Blues prepare for this weekend's Emirates FA Cup final but, speaking to nufc.co.uk, he admitted that he'd thoroughly enjoyed his time on Tyneside.
"I was glad to come here to Newcastle, one of the biggest clubs in England, and I really appreciated the chance to play," he said. "I'd like to thank Rafa Benítez because he trusted in me. I really enjoyed my time here - it was very good.
"All the players, all the staff, they made me feel at home. I felt good. I gained confidence from the amazing support and I really enjoyed it. Maybe one day I will be back."
Kenedy claimed an assist for Jamaal Lascelles on his Newcastle debut against Burnley, as well as winning a penalty in a 1-1 draw at St. James' Park, and never looked back from that point.
"The first game - my debut - was really, really good because I didn't expect something like this," he smiled. "And the game against Leicester was amazing because I'd never seen support like that.
"The supporters were really amazing. I really appreciate that because I didn't expect anything like this.
"The fans were something different. I felt honoured to be here; it was something really special and I'm a fan of Newcastle's fans."
