The 23-year-old made his Ulster debut against Benetton in January 2016 and has gone on to make 63 appearances, scoring 27 tries.
"I am delighted to have signed an IRFU contract," he said.
"I am involved with two ambitious squads and I know I will continue to develop as a player in both environments."
David Nucifora, IRFU Performance Director, sees more potential in Stockdale: "Jacob has continued to grow as a player after bursting onto the scheme in his debut Six Nations season.
"He has performed at a consistently high level for both Ireland and Ulster and has huge potential to develop further on the international stage."
