Street art, also known as urban art or graffiti art, is a form of artistic expression that is created in public spaces, typically using various techniques such as spray paint, stencils, stickers, posters, and installations.
It emerged as a subculture and artistic movement in the late 20th century and has since gained recognition and popularity around the world.

Street art is often associated with the urban environment and serves as a means for artists to communicate their messages, challenge social norms, and reclaim public spaces.
It can take many forms, including murals, graffiti tags, stencil art, wheat-pasting, and 3D installations. Artists use these mediums to express their creativity, make political or social statements, or simply add color and vibrancy to urban landscapes.
