A Post-it note (or sticky note) is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-tack pressure-sensitive adhesive allows the notes to be easily attached, removed and even re-posted elsewhere without leaving residue. The Post-it's signature adhesive was discovered accidentally by a scientist at 3M.[1] Originally small yellow squares, Post-it Notes and related products are available in various colors, shapes, sizes and adhesive strengths. As of 2024, there are at least 28 documented colors of Post-it notes.[2] 3M's Post-it has won several awards for its design and innovation.[3]

Post-its are versatile and can be used in various settings for various purposes.[4] They are commonly used in classrooms and workplaces but can also be found in art, media, and social media.[4][5][6][7] Post-its have also been used as tools for public engagement and persuasion.[8][9][10]

Although 3M's patent expired in 1997, "Post-it" and the original notes' distinctive yellow color[11] remain registered company trademarks, with terms such as "repositionable notes" used for similar offerings manufactured by competitors. While use of the trademark 'Post-it' in a representative sense refers to any sticky note, no legal authority has ever held the trademark to be generic.[a]
