数学与物理学中，潘洛斯图形符号（英语：Penrose graphical notation）或称张量图符号（tensor diagram notation）是多线性函数或张量的一种图形表示法，由罗杰·潘洛斯所提出。

这样的图有多种几何图案，之间由线段相连。Predrag Cvitanović曾深入研究此方法，将之用在古典李群的分类上。

透过表示论，此方法也被推广至物理学中的自旋网络，以及线性代数中矩阵群相关的迹数图。

In mathematics and physics, Penrose graphical notation or tensor diagram notation is a (usually handwritten) visual depiction of multilinear functions or tensors proposed by Roger Penrose. A diagram in the notation consists of several shapes linked together by lines. The notation has been studied extensively by Predrag Cvitanović, who used it to classify the classical Lie groups. It has also been generalized using representation theory to spin networks in physics, and with the presence of matrix groups to trace diagrams in linear algebra.
