Joss sticks are a type of incense used in many East Asian and Southeast Asian countries, traditionally burned before a Chinese religious image, idol or shrine. They can also be burned in front of a door, or open window as an offering to heaven, or devas. In modern days, joss sticks can be used for any purpose, such as to enhance the smell of a room, or to light fire crackers.

Joss sticks are religious materials in China, India, Bangladesh, Vietnam, Thailand, Taiwan, Myanmar, Cambodia, Philippines, Korea,and Japan.

The word "joss" is derived from the Latin deus (god) via Portuguese.

Joss stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used.
