Cavan reached the Liberty Insurance Premier Junior Camogie All Ireland Final following a 2-16 to 1-6 win over Roscommon on Saturday.
Shauna Fallon opened the scoring for Roscommon with a goal after 5 minutes but Cavan fought back to draw level at the break.
The Breffni women then dominated the second half and a goal each from Roisin O'Keefe and Shanise Fitzsimons helped them to a 13 point win.
Cavan Manager Jimmy Greville was pleased with his side's performance.
Cavan will now play Armagh in the final, after the Orchard county overcame Tyrone.
