We say that the square matrices $A$ and $B$ are of the same order quasi-commute if $AB=\sigma BA$ for some scalar $\sigma$. Classical relations of commutation and anti-commutation are particular cases of this definition. We give a complete description of pairs of the quasi-commuting Toeplitz and Hankel matrices for $\sigma\ne\pm1$.
