Ireland secured a fourth Triple Crown in five years with a commanding 43-21 bonus-point victory over Scotland at the Aviva Stadium, but their hopes of a Six Nations title were dashed as defending champions France beat England 48-46 with the last kick of the tournament.
Andy Farrell's side extended their remarkable dominance over Scotland to 12 consecutive wins, temporarily moving top of the championship table. However, France's dramatic victory in the final match of 'Super Saturday' pushed Ireland into second place, denying them the ultimate prize and a St Patrick's weekend celebration.
Scotland finished third in the standings, falling short in their quest for a first Triple Crown since 1990 and a maiden Six Nations title. The match in Dublin was a frenetic affair, with Ireland full-back Jamie Osborne and Scotland wing Darcy Graham each scoring their fourth tries of the tournament in the opening exchanges.
Dan Sheehan and Robert Baloucoune added tries for Ireland to give the hosts a 19-7 half-time lead. Scotland fought back in the second half through Finn Russell and Rory Darge, but Ireland's replacements, including Darragh Murray and Tommy O'Brien, sealed the win with late scores.
Scotland had arrived in Dublin brimming with confidence after their stunning 50-40 victory over France the previous week, but they were unable to replicate that form. Ireland's victory was built on a dominant set-piece and clinical finishing, with Jack Crowley contributing 13 points off the tee.
