Flights will run twice weekly on Tuesdays and Saturdays from 3 May. The new route will go on sale later this week.
The addition comes as the carrier celebrates 20 years of flying from Gatwick.
The airline has reportedly carried more than 200 million passengers to and from the London airport across the last two decades and has added more than 1.1 million additional seats for next summer.
Ali Gayward, easyJet’s UK country manager, said the airline has "remained committed" to "providing even more choice" for its customers travelling to and from the airport over the last 20 years.
"We recently added over a million extra seats from the airport for next summer and new routes such as our new flights to Krk off the coast of Croatia, continuing to provide passengers with an ever-greater range of destinations," she added.
