PL/I (Programming Language One, pronounced ) is a procedural, imperative computer programming language designed for scientific, engineering, business and system programming uses. It has been used by various academic, commercial and industrial organizations since it was introduced in the 1960s, and continues to be actively used.

PL/I's main domains are data processing, numerical computation, scientific computing, and system programming; it supports recursion, structured programming, linked data structure handling, fixed-point, floating-point, complex, character string handling, and bit string handling. The language syntax is English-like and suited for describing complex data formats, with a wide set of functions available to verify and manipulate them.
