Shoeshiner or boot polisher is an occupation in which a person cleans and buffs shoes and then applies a waxy paste to give a shiny appearance and a protective coating. They are often known as shoeshine boys because the job was traditionally done by a male child. Other synonyms are bootblack and shoeblack. While the role is denigrated in much of Western civilization, shining shoes is an important source of income for many children and families throughout the world. Some shoeshiners offer extra services, such as shoe repairs and general tailoring. Some well-known people started their working life as shoeshiners, including singers and presidents.

Shoe polish, also known as boot polish and shoeshine, is a waxy paste, cream, or liquid that is used to polish, shine, and waterproof leather shoes or boots to extend the footwear's life and restore its appearance. Shoe polishes are distinguished by their textures, which range from liquids to hard waxes. Solvent, waxes, and colorants comprise most shoe polishes. Shoe polish has been around since medieval times, originally made with dubbin. Originally, it was not used to shine shoes; the popularity of shoeshining that rose during the early 1900s led to many shoe polish formulas being incorporated with a shining agent.
