In this paper, we de fined new subclasses of Spirallike and Robertson functions by using concept of q-derivative operator. We investigate convolution properties and coefficient estimates for both classes q-Spirallike and q-Robertson functions denoted by S-q(lambda) [A,B] and C-q(lambda) [A,B], respectively.
