烛光集会又称烛光晚会，是一种具特定主题的和平示威集体社会活动。

主要以烛光作最主要道具，多在上半夜（即傍晚起至凌晨）举行。也因为点燃白色的洋烛及小火光的缘故，因此称这类的集会为烛光集会，相对于一般游行或是示威等群众运动来说，烛光集会多办具备较为温馨的性质。随着智能型手机的普遍，烛光也可能以手机的LCD触摸屏幕发光取代。集会多以记念某些节日、社会现象、历史事件或者悼念为主题，人群聚集在球场、草地或广场一角。晚会中有记念的目标人物及事件；为营造特定气氛，场地多有布景、有横额、有主题音乐及背景音乐、主办单位有讲话，甚至喊口号等，但烛光晚会前后较少以游行活动接续。

A candlelight vigil is an outdoor assembly of people carrying candles, held after sunset in order to show support for a specific cause. Such events are typically held either to protest the suffering of some marginalized group of people, or in memory of a life or lives lost to some disease, disaster, massacre or other tragedy. In the latter case, the event is often called a candlelight memorial. A large candlelight vigil will usually have invited speakers with a public address system and may be covered by local or national media. Speakers give their speech at the beginning of the vigil to explain why they are holding a vigil and what it represents. Vigils may also have a religious or spiritual purpose. On Christmas Eve many churches hold a candlelight vigil.
