The news comes on the back of a highly-publicised walkout by Liverpool fans last Saturday which saw an estimated 10,000 supporters leave Anfield in the 77th minute of the 2-2 draw with Sunderland.
Liverpool fans are upset with the club's pricing structure for 2016-17, which included a £77 match ticket and a top-priced season ticket of £1,029.
Newcastle believe there is a risk "generations of supporters" could be lost if the cost of attending matches rises too high.
Newcastle managing director Lee Charnley said: "While the debate around Premier League ticket prices continues, we want to ensure watching football at St James' Park remains affordable for as many people as possible.
"There is a clear risk that clubs could lose generations of supporters with the cost being a major factor and we have considered that when setting prices for 2016-17.
"We want to encourage more families to attend and ensure that the price of a ticket does not become a barrier for our youngest supporters."
Season tickets for juniors at Newcastle will start at £57 and some individual match tickets for children will be just £3.
The full pricing scheme will be confirmed in the coming weeks but season ticket renewal letters are currently being processed.
The club have also announced they will continue to seek reciprocal deals with other clubs to keep the prices of tickets for away fans affordable.
