The Lemuralia or Lemuria was a feast in the religion of ancient Rome during which the Romans performed rites to exorcise the malevolent and fearful ghosts of the dead from their homes. The unwholesome spectres of the restless dead, the lemures or larvae were propitiated with offerings of beans. On those days, the Vestals would prepare sacred mola salsa, a salted flour cake, from the first ears of wheat of the season.

In the Julian calendar the three days of the feast were 9, 11, and 13 May. The myth of origin of this ancient festival, according to Ovid, who derives Lemuria from a supposed Remuria was that it had been instituted by Romulus to appease the spirit of Remus (Ovid, Fasti, V.421ff; Porphyrius ). Ovid notes that at this festival it was the custom to appease or expel the evil spirits by walking barefoot and throwing black beans over the shoulder at night. It was the head of the household who was responsible for getting up at midnight and walking around the house with bare feet throwing out black beans and repeating the incantation, "I send these; with these beans I redeem me and mine (haec ego mitto; his redimo meque meosque fabis.)." nine times. The household would then clash bronze pots while repeating, "Ghosts of my fathers and ancestors, be gone!" nine times.
Because of this annual exorcism of the noxious spirits of the dead, the whole month of May was rendered unlucky for marriages, whence the proverb Mense Maio malae nubent ("They wed ill who wed in May").
On what had been the culminating day of the Lemuralia, May 13 in 609 or 610— the day being recorded as more significant than the year—, Pope Boniface IV consecrated the Pantheon at Rome to the Blessed Virgin and all the martyrs, and the feast of that dedicatio Sanctae Mariae ad Martyres has been celebrated at Rome ever since. According to cultural historians, this ancient custom was Christianized in the feast of All Saints' Day, established in Rome first on May 13, in order to de-paganize the Roman Lemuria, while others see a link to the May 13 date in Saint Ephrem's celebration of All Saints on that day in the 4th century.

- "they do not occur in epitaphs or higher poetry," George Thaniel noted (in "Lemures and Larvae" The American Journal of Philology 94.2 [Summer 1973, pp. 182-187] p 182) remarking "The ordinary appellation for the dead in late Republican and early Imperial times was Manes or Di Manes, although frequent use was also made of such terms as umbrae, immagines, species and others." He notes the first appearance of lemures in Horace, Epistles ii.2.209.
- Modern linguists dismiss this connection but find the etymology of lemures obscure.
- Manes exite paterni! is the formula given by Ovid (Fasti V.443); scholars argue over how accurate Ovid was in this instance.
- See for example "Days of the Dead" in Christian Roy, ed. Traditional festivals: a multicultural encyclopedia, 2005, vol. 2: s.v. "All Saints' Day and Halloween": "...yet May 13 had also happened to be the last day of the Roman Lemuria for lost souls"; Richard P. Taylor, Death and the Afterlife: a cultural encyclopedia 200, p. 163: "Pope Boniface IV (608-615) replaced Lemuria with "All Saints' Day" on 13 May."
- An attempt to connect the cultus of All Saints' and All Souls' Day with the Roman Parentalia, observed however in February, is sometimes made: e.g. Gordon J. Laing, Survivals of Roman Religion (Boston 1931) p. 84: "...the thirteenth of May, which was one of the days of the Roman festival of the dead, the Lemuria. Whether there is any connection between these dates or not, the rites of All Saints' Day are a survival not of the Lemuria but of the Parentalia."
