The charity hopes that researchers who know about the NSPCC's work will encourage MPs to take up child protection issues in Parliament or visit its services in their constituencies.
Charlotte Smith, parliamentary adviser at the NSPCC said: "Researchers write MPs' speeches, organise their diaries and do a lot behind the scenes.
"They often go on to do significant jobs. This is a really good chance to inform them before they go off and do high-powered jobs themselves."
The network, which will be launched at Westminster tomorrow, will initially be internet-based.
Researchers who sign up will receive email bulletins and briefings. Smith hopes to organise other events in future - possibly with other organisations.
"I'm open to doing joint events," she said. "There are quite a lot of areas, particularly legislation, in which we work with other charities."
