We provide a criterion for the equivalency of the second-kind involutions of upper triangular matrix algebras over commutative rings. For an algebra $T_{n}(F)$ of upper triangular matrices over a field $F$ it is proven that two involutions are equivalent if and only if they coincide after restriction to $F$.
Keywords: upper triangular matrix algebra, involution, equivalency of involutions.
