In the present paper, we introduce the notion of generalized left derivation of a BCI-algebra X, construct several examples, and investigate related properties. Also establish some results on regular generalized left derivation. Furthermore, for a generalized left derivation H, the concept of a H-invariant generalized left derivation is introduced, and examples are discussed. Using this concept a condition for a generalized left derivation to be regular is provided. Finally, some results on p-semisimple BCI-algebra are obtained and it is shown that let H be a self map in a p-semisimple BCI-algebra X. Then H is a generalized left derivation if and only if it is a derivation on X.
