John Sullivan's side will secure a second title in a row with a win away to Cork City.
Athlone Town are now within touching distance of securing back to back titles in the Women's Premier Division.
John Sullivan's side secured a 2-1 win away to Shelbourne on Saturday.
Town struck first just before half time when Hannah Waesch finished smartly from close range, with Kelly Brady doubling the lead on the counter, moving level at the top of the scoring charts.
Shelbourne fought back, with Jemma Quinn's header setting up a tense finale, but Sullivan's troops held out to leave them four points clear with a game in hand.
A win away to Cork City this Wednesday will be enough to claim a second title in a row.
