Walkman (Japanese: ウォークマン, Hepburn: Wōkuman) is a brand of portable audio players manufactured by Sony since 1979. It was originally introduced as a portable cassette player and later expanded to include a range of portable audio products. Since 2011, the brand has referred exclusively to digital flash memory players.

The Walkman became widely popular during the 1980s for its portable design and private listening experience. It influenced popular culture by promoting individualized music consumption and supporting activities such as aerobics. Its widespread use gave rise to the "Walkman effect," a term describing how portable music devices and headphones allow listeners to control their sonic environment. In 1986, "Walkman" was added to the Oxford English Dictionary, and in some markets the term became a genericized trademark for portable audio players. The Walkman also contributed to the widespread adoption of the Compact Cassette format, which surpassed vinyl record sales in 1983. Sony sold approximately 220 million cassette-based Walkman units before ending production in 2010.

Sony also achieved commercial success with its CD-based models (originally marketed as the Discman, later rebranded as the CD Walkman), and by 2010, cumulative sales of all Walkman devices had reached around 400 million units. However, despite extensive marketing efforts, MiniDisc Walkman devices remained a niche product. In the digital era, Sony was unable to replicate the brand’s earlier success, as Apple's iPod range gained widespread popularity and limited international Walkman sales.

The Walkman’s influence on consumer electronics has been compared to later devices such as mobile phones and personal computers.
