A portable application, or portable app for short, is a computer software program that does not need to be installed or copied onto a computer’s mass storage device to be executed, running instead from a removable storage device such as a CD-ROM drive, USB flash drive, flash card, or floppy disk.

Portable applications can be run on any computer system with which they are compatible; they usually require a certain type of operating system (e.g., Microsoft Windows XP or above, any Linux, etc). Portable software in this sense should not be confused with software portability, where software is designed in a way which allows its source code to be compiled for different computing platforms.
