Bubble wrap, bubble pack or bubble paper is a pliable transparent plastic material commonly used for packing fragile items. Regularly spaced, protruding air-filled hemispheres (bubbles) provide cushioning for fragile items.

The term is also a brand of Sealed Air Corporation (US). In 1957 two inventors named Alfred Fielding and Marc Chavannes were attempting to create a 3-dimensional plastic wallpaper. Although the idea was a failure, they found that it did make for great packing material. Sealed Air Corp. was co-founded by Alfred Fielding in 1960.

Some people use the name generically for similar products, often termed air bubble packing, bubble wrapping or aeroplast; Sealed Air denotes its product as a brand of "cushioning material".
