Áilleacht (or Áilleacht: Beauty) is the sixth studio album from Irish singer Pádraigín Ní Uallacháin, the fifth to be released on the Gael Linn label.

The album's central theme is love, with songs mainly written by Ní Uallacháin.

Fantasy novelist O. R. Melling used verses from both "Gleann na nDeor" (Valley of Tears) and "An Phóg" (The Kiss), in this novel "The Light-Bearer's Daughter".

Writing in The Journal of Music, poet Louis de Paor stated, "this is a deceptively sophisticated composition in which a profound emotional disturbance is articulated apparently without artifice, impressing itself on the listener as though it were actual and direct speech.

It is a fitting conclusion to a substantial and deeply satisfying piece of work.
