Gregory's health had worsened after he left Lyons in April 1275. He was suffering from a hernia, and so he was forced to stop frequently on the way back to Rome. He departed Vienne shortly after 30 September 1275 and arrived in Lausanne on 6 October 1275.<ref>August Potthast, ''Regesta Pontificum Romanorum'' II (Berlin 1875), p. 1700</ref> In Lausanne, he met with the Emperor-elect [[Rudolf I of Germany|Rudolf of Habsburg]], King of the Romans, and on 20 October 1275, received his oath of fealty.<ref>Pietro Campi, ''Dell' historia ecclesiastica di Piacenza'' II (Piacenza 1662), p. 483.</ref> On Tuesday, 12 November 1275, he was in Milan. His party reached Reggio Aemilia on 5 December 1275, and they were in Bologna on 11 December 1275. A severe rise in his temperature and the presence of the hernia forced him to a halt at Arezzo in time for Christmas of 1275. His condition rapidly declined following this and led to his death on 10 January 1276. He is buried inside the Cathedral Church of Arezzo.

He was succeeded by the Dominican Peter of Tarantaise of Savoy ([[Pope Innocent V]]), a close collaborator of the pontiff throughout his pontificate.<ref>{{Cite web|url=http://www.csun.edu/~hcfll004/SV1276.html|title=SEDE VACANTE|website=www.csun.edu}}</ref>
