The new routes, which will be operating by the end of October, will operate daily from Stansted to Grenoble, Kaunas, Lodz and Poznan.
In addition Ryanair is also increasing the frequency on its existing routes from Stansted to Derry, Seville, Granada, Riga and Tampere.
Ryanair chief executive Michael O'Leary said: "We launched our first route in Poland just three months ago from London Stansted to Wroclaw and with these two new routes to Lodz and Poznan, Ryanair will serve more Polish airports (seven) directly from London that any other airline. We're delighted also to announce our first new route to Kaunas in Lithuania. This route will operate daily and Ryan Air expects to carry in excess of 100,000 passengers in our first year of operation.
