High Performance Fortran（有时简称：HPF）是一种编程语言，它延伸自Fortran 90编程语言，高性能Fortran是为了支持并行计算所创设的编程语言，它使用一种SIMD的运算型态，使运算工作能够进行分拆，并以扩散方式发派到运算数组中的各颗处理器上，以此达到高性能计算。

HPF有一种forall语法可以同时更新平行运算中的整组数组派项，这项语法自Fortran 95之后开始具备，除此之外forall语法也提供建议（或称：提示、指点），建议在平行运算系统中处理器间应如何协同工作。

High Performance Fortran (HPF) is an extension of Fortran 90 with constructs that support parallel computing, published by the High Performance Fortran Forum (HPFF). The HPFF was convened and chaired by Ken Kennedy of Rice University. The first version of the HPF Report was published in 1993.
