This study is devoted to the Jordan automorphisms of Tn+1 (R) that is the algebra of all upper triangular (n + 1) by (n + 1) matrices over a commutative ring R with ??? identity. Main Jordan and Lie automorphisms are presented. These are graph, central, diagonal and inner automorphisms. In this section it is also studied Jordan and Lie automorphisms of Tn+1(R) which is an algebra over a commutative and 2-torsion free ring R with identity.
