Wing Alyssa D'Incà (ITA), fullback Ellie Kildunne (ENG), and back rowers Romane Menager (FRA) and Aoife Wafer (IRE) are the nominees for the individual accolade - voting for which is now open.
The 22-year-old D'Incà scored three tries in this year's Championship, and her all-round game saw her feature in the Fantasy Team of the Week on four occasions (one of only two players to do so - the other being Kildunne).
Kildunne, 24, scored a minimum of two tries all the way up to Super Saturday, ultimately crossing the whitewash on nine occasions as John Mitchell's Red Roses sought to - and succeeded in - making their backs as potent a weapon as their forwards.
Menager was at the forefront of Les Bleues' unbeaten charge to the Super Saturday decider with England. The 27-year-old ranked sixth for metres carried (404.4, gaining 262.8) and joint-third for offloads (six),
Ireland's renaissance in 2024 was perhaps best epitomised by the emergence of Wafer, 21, as a force to be reckoned with. She carried for 417 metres (gaining 264.8), scored two tries, and ranked fourth for linebreaks (six).
Voting closes 22:00 BST on Tuesday 7th May. The four nominees have been selected on the basis of the number of fan votes each received for the Team of the Championship - from which a maximum of one nominee from any nation was able to be selected.
