In computer science, Cannon's algorithm is a distributed algorithm for matrix multiplication for two-dimensional meshes first described in 1969 [1] by Lynn Elliot Cannon.

It is especially suitable for computers laid out in an N × N mesh [2]. While Cannon's algorithm works well in homogeneous 2D grids, extending it to heterogeneous 2D grids has been proven to be difficult.[3]

The main advantage of the algorithm is that its storage requirements remain constant and are independent of the number of processors [1].
