It’s the third year running that Liberton, a rising force in the junior game, have been involved in the title showdown.
They made it again after beating Dalmahoy 4-3 in a close-fought semi-final at Ratho Park.
Callum Cochrane, Josh Rooney and Graham Ross won for Dalmahoy but Ross Munro, Scott Finlay, Fraser Christie and John Butler delivered the all-important points for Liberton.
Musselburgh beat Silverknowes in the other semi-final.
Dalmahoy and Silverknowes also meet at Prestonfield tomorrow to decide the third team to represent the Edinburgh League in the Scottish Finals being held this year at Cardrona.
