Beltane ( /ˈbɛlteɪn/) is the anglicised spelling of the Goidelic name for either the month of May or the festival held on the first day of May. In Irish Gaelic it is Bealtaine ([ˈbʲal̪ˠt̪ˠənʲə]), in Scottish Gaelic Bealltainn ([ˈbʲal̪ˠt̪ˠənʲ]) and in Manx Gaelic Boaltinn or Boaldyn.

Beltane was an ancient Gaelic festival celebrated in Ireland, Scotland and the Isle of Man. It marked the beginning of summer and was linked to similar festivals held elsewhere in Europe, such as the Welsh Calan Mai and the Germanic Walpurgis Night. Beltane and Samhain were the leading terminal dates of the civil year in medieval Ireland, though the latter festival was the more important. It is a cross-quarter day, marking the midpoint in the Sun's progress between the spring equinox and summer solstice. The astronomical date for this midpoint is nearer to 5 May or 7 May, but this can vary from year to year.

Beltane regained popularity during the Celtic Revival and is still observed as a cultural festival by some in Ireland, Scotland, the Isle of Man and among their diasporas. Today, Beltane is also observed as a religious festival by Celtic neopagans. Wiccans adopted the name Beltane for their May festival.

Loreena Isabel Irene McKennitt, CM, OM (born February 17, 1957) is a Canadian singer, composer, harpist, accordionist and pianist who writes, records and performs world music with Celtic and Middle Eastern themes. McKennitt is known for her refined, clear soprano vocals. She has sold more than 14 million records worldwide.

McKennitt was born in Morden, Manitoba of Irish and Scottish descent to parents Jack (died 1992; a livestock dealer) and Irene McKennitt (1931-2011; a nurse). She moved to Stratford, Ontario in 1981, where she still resides.

When Loreena was young she wanted to become a veterinarian but she found that music chose her rather than she it. Developing a passion for Celtic music, she learned to play the Celtic harp and began busking at various places, including St. Lawrence Market in Toronto in order to earn money to record her first album.

McKennitt's first album, Elemental, was released in 1985, followed by To Drive the Cold Winter Away (1987), Parallel Dreams (1989), The Visit (1991), The Mask and Mirror (1994), A Winter Garden (1995), The Book of Secrets (1997), An Ancient Muse (2006), A Midwinter Night’s Dream (2008), and The Wind That Shakes the Barley (2010). All of her work is released under her own label, Quinlan Road.
