Argentine ace Fabricio Coloccini will continue to lead the Magpies next term, but Alan Pardew has moved to appoint two vice-captains in the shape of De Jong and Cheick Tiote.
"At Newcastle, I have great faith in Fabricio Coloccini, but we have also just last week announced two official vice-captains in Cheick Tiote and Siem De Jong, who was captain at Ajax, giving us three players from different areas of the pitch to take that bit of extra responsibility," Pardew said in his Independent column.
Coloccini has captained Newcastle since 2011, and Pardew is delighted to still count on the South America, who failed to make Argentina's World Cup squad.
"Coloccini is a relatively quiet lad, who leads by example and presence and his calmness on the ball," he said.
"The most vocal guy does not necessarily mean the best leader, although previously we had Kevin Nolan, who was very vocal in the dressing-room and a great organiser of the group."
