The iPod Classic (trademarked, marketed, and stylized as iPod classic and known before its sixth generation as simply iPod) is a portable media player marketed by Apple Inc. The current generation is by far the most capacious iPod, with 160GB of storage.

To date, there have been six generations of the iPod, as well as a spin-off (the iPod Photo) that was later re-integrated into the main iPod line. (Some sources incorrectly refer to the revisions of the sixth generation as a separate "seventh generation.") All generations use a 1.8-inch (46 mm) hard drive for storage. The "classic" suffix was initially introduced when a freelance writer analyzing eBay's used/broken iPod marketplace categorized iPods into different types on May 21, 2006 and was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007 prior to this, all iPod models were simply referred to as iPods. It is available in silver or black replacing the "signature iPod white".

Apple introduced the first-generation iPod on October 23, 2001, with the slogan "1,000 songs in your pocket". The first iPod had a black and white LCD (liquid-crystal display) screen and featured a 5 GB hard drive capable of storing 1,000 songs encoded using MP3 and was priced at US$399. Among the iPod's innovations were its small size, achieved using a 1.8" hard drive, whereas its competitors were using 2.5" hard drives at the time, and its easy-to-use navigation, which was controlled using a mechanical scroll wheel (unlike later iPods, which had touch-sensitive scroll wheels), a center select button, and four auxiliary buttons around the wheel. The iPod had a rated battery life of ten hours.
