In this paper, the unsteady oscillatory flows of a generalized Burgers' fluid in a rotating frame are investigated. The constitutive equations of the generalized Burgers' fluid are used in the mathematical formulation of the problem. The solutions are obtained by using the Laplace transform method. The graphical results are displayed and discussed for various parameters of interest. It is found that the velocity profiles reflect some interesting results for the rotation parameter and rheological fluid parameters.

*Key words:* Oscillatory Flow; Generalized Burgers' Fluid; Rotating Frame.
