In this paper, we introduce and study the notion of left ϕ-essential Connes amenable for dual Banach algebras. We investigate the hereditary properties of this new concept and we give some results for θ-Lau product and module extension. For unital dual Banach algebras, we show that left ϕ-essential Connes-amenability and left ϕ-Connes amenability are equivalent. Finally, with various examples, we examined this concept for upper triangular matrix algebras and l1-direct sum of Banach algebras.
