The pack is unchanged from last week's team which faced Connacht at Kingspan Stadium.
There's an all-Cooke front row, made up of Sadhbh McGrath, Megan Simpson and Ilse Van Staden, with Keelin Brady and Brenda Barr pairing up in the second row.
Enniskillen duo India Daley and Sophie Barrett retain their places in the back row at 6 and 8 respectively, with captain Beth Cregan again starting at openside flanker.
Rachael McIlroy and Ella Durkan continue their pairing in the half-back positions, with Kelly McCormill moving from outside to inside centre.
Emma Jordan comes into the starting lineup at 13, with Lucy Thompson brought in on the right wing. Left wing Niamh Marley and fullback Maeve Liston will start their third consecutive game of the Championship.
The replacements are Aishling McConnell, Gemma McCamley, Fiona Tuite, Helen McGhee, Stacey Sloan, Hannah Beattie, Hannah Downey, and Fern Wilson.
Captain Beth Cregan
"The initial reaction to last Saturday's result, it was disheartening. Especially in that second half, we really felt the comeback was there for us, but unfortunately a few things just didn't go our way and chasing a game becomes very hard. But we have shown that when we get things to click, we are a very threatening team, and there are definitely positives to be taken away from that performance.
"No matter how performances go though, we move on to the next game, and from watching Leinster it's clear they want to play an expansive brand of rugby. We expect them to run it from everywhere, kick deep, look for offloads, and play with a bit of flair - but we want to nullify that, and show our own style.
"We're really looking forward to this game and hoping we can put down a marker and start games the same way we've been finishing them. We want to really push on and get that whole 80 minute performance."
