圣布里吉德节（英语：St Brigid's Day，苏格兰盖尔语：Là Fhèill Brìghde，爱尔兰语：Lá Fhéile Bríde），又称为Imbolc、圣烛节（Candlemas），是一个凯尔特节日，以庆祝春天的到来。北半球的圣布里吉德节通常在2月1日或2日（旧历为2月12日），南半球则在8月1日。这一天大致在冬至与春分的中间。

中世纪时盖尔族爱尔兰就已在庆祝这一节日。Imbolc这一名称来称于爱尔兰神话阿尔斯特故事（Ulster Cycle）的一则故事Tochmarc Emire之中，Imbolc与Beltane、Lughnasadh、Samhain同为四个跨季节日（cross-quarter day）之一。该节日被认为可能是一个与女神布里吉德（Brigid，非圣布里吉德）有关的异教节日。

Imbolc or Imbolg (pronounced i-MOLG), also called (Saint) Brigid's Day (Irish:Lá Fhéile Bríde, Scottish Gaelic:Là Fhèill Brìghde, Manx:Laa'l Breeshey), is a Gaelic festival marking the beginning of spring. Most commonly it is held on 1 February, or about halfway between the winter solstice and the spring equinox. Historically, it was widely observed throughout Ireland, Scotland and the Isle of Man. It is one of the four Gaelic seasonal festivals—along with Beltane, Lughnasadh and Samhain—and corresponds to the Welsh Gŵyl Fair y Canhwyllau. Christians observe it as the feast day of Saint Brigid, especially in Ireland.
