The Leesiders regained the title they had previously won in 2017 by defeating Galway in the Final at Parnell Park last May. Along the way they had beaten Dublin in a dramatic extra-time encounter.
2019 runners-up Galway, who also contested the TG4 All-Ireland Senior Final, will have home advantage against Waterford as they kickstart their new season in the opening round of National League fixtures.
Elsewhere, TG4 All-Ireland Senior Champions Dublin will play host to the TG4 All-Ireland Intermediate winners Tipperary, while Donegal make the trip to Mayo on the opening day.
Looking ahead, Dublin have three mouth-watering fixtures to look forward to in Rounds 2, 3 and 4, when they face Mayo away from home, before welcoming Cork and Galway to the capital on successive weekends.
Dublin beat Galway in front of a record 56,114 attendance in the 2019 TG4 All-Ireland Final, to land the Brendan Martin Cup for a third successive year.
In Division 2, Cavan host Kerry, Armagh make the trip to Clare, Meath entertain Tyrone, and Monaghan are the visitors to Wexford in the opening round.
In Division 3, Round 1, Fermanagh are at home to Kildare, Laois take on Wicklow in an all-Leinster affair, Longford are up against Down, and there’s a Connacht derby between Roscommon and Sligo.
And in Division 4, Antrim take on Offaly, Carlow are at home to Limerick, while Leitrim make the trip to Derry.
The LGFA has also confirmed that the top two finishers will progress straight to the Finals in each of the divisions. The 2020 Lidl Ladies National Football League Finals will be played on the weekend of April 18/19.
It remains to be seen in the coming weeks whether we will be able to look forward to a number of double headers with the Allianz League once that gets under way heralding another year of great Gaelic Games action.
