The object of the present paper is to introduce and investigate new subclasses of the function class $\Sigma$ of bi-univalent functions defined in the open unit disk U, involving quasi subordination. The coefficients estimate $|a_2|$ and $|a_3|$ for functions in these new subclasses are also obtained.
