A candle snuffer, candle extinguisher, or douter is an instrument used to extinguish burning candles, consisting of a small cone at the end of a handle. The use of a snuffer helps to avoid problems associated with blowing hot wax and it avoids the smoke and odor of a smoldering wick which results from simply blowing a candle out. Extinguishers are still commonly used in homes and churches.

Before the mid 19th century, the term snuffer referred to a scissors-like device with two flat blades and an attached snuffer box. This tool was used to trim the wick of a candle without extinguishing the flame, to maintain efficient burning.
