The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by William C. Lowe and Philip Don Estridge in Boca Raton, Florida.

The machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it.

The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from Apple's Macintosh product line, as well as consumer-grade platforms created by companies like Commodore and Atari. Most contemporary personal computers share architectural features in common with the original IBM PC, including the Intel-based Mac computers manufactured from 2006 to 2022.
