The total graph of a finite commutative ring with unity, denoted by \(T(\Gamma (R))\) , consists of vertices representing the elements of R. Two distinct vertices x and y are connected if their sum \(x+y\) belongs to the set Z(R), which represents the set of zero-divisors of R. This paper provides the necessary condition for the existence of the metric dimension of total graph of a finite commutative ring. A bound for the metric dimension has been obtained and with this context rings have been characterized for which the metric dimension of total graph attains a sharp bound. Additionally, the relationship between the metric dimension of total graph and other graph invariants have been developed.
