In this letter, the Lie point symmetries of the time fractional Fisher (TFF) equation have been derived using a systematic investigation. Using the obtained Lie point symmetries, TFF equation has been transformed into a different nonlinear fractional ordinary differential equations with the Erd´elyi–Kober fractional derivative which depends on the parameter α. After that some invariant solutions of underlying equation are reported.
