Abstract. In this paper our attempt is to extend the notion of essential fuzzy ideals of rings to T-fuzzy essential ideals. Various properties on T-fuzzy essential ideals are established. Some results are being discussed which establish necessary and sufficient condition between T-fuzzy essential ideal in fuzzy set theory and essential ideal in crisp set theory. Moreover it is proved that if $\mu, \nu$ and $\sigma$ are non-zero T-fuzzy left ideals of $R$ such that $\mu\subseteq\nu\subseteq\sigma$, then $\mu\subseteq_{e(T)}\sigma$ if and only if $\mu\subseteq_{e(T)}\nu\subseteq_{e(T)}\sigma$.
