President Petro Poroshenko said it was a "brilliant operation", which showed Ukraine`s fight against art smuggling.
The paintings include works by Tintoretto and Rubens.
They were stolen from Verona`s Castelvecchio museum in November 2015.
Three masked armed men entered the building after it closed for the day and just before the alarm system was activated.
They quickly overpowered a security guard and a cashier, before escaping with the paintings in a car.
Last month, 13 suspects were arrested in Italy and Moldova, the Italian authorities said.
President Poroshenko said Italian art experts would now be invited to Ukraine to authenticate the paintings and formalise their handover.
