The squad will meet up on Saturday ahead of the UEFA 2019 Under-21 European Championships qualifying match against the Norwegians in Marienlyst Stadion, Drammen, with kick-off at 7pm (6pm local time).
King has gone for a largely-unchanged squad with his side currently top of qualifying group five on 10 points having claimed three wins out of their opening four matches. Liverpool goalkeeper Caoimhin Kelleher comes in for Nottingham Forest's Liam Bossin in the only change with Bossin sidelined through injury.
Fourth-placed Norway held Ireland to a 0-0 draw at Tallaght Stadium in October and will need to win on Tuesday to keep any qualification hopes alive whilst Ireland will be looking to continue their unbeaten start to the campaign.
Republic of Ireland Under-21 Head Coach Noel King said: "The squad is really looking forward to meeting up later in the week and starting our preparations for the trip to Norway.
"As the Norwegians proved in the game in October, they are a very good team who will provide us with a difficult test. The players have started the campaign brilliantly and to be in the position at the top of the table after four games is fantastic and a credit to them.
"Norway will be boosted by their 3-1 victory against Germany and nobody is in doubt about the enormity of the challenge we face but given the levels these lads have reached, nothing would surprise me from them."
