A new extended cubic B-spline approximation for the numerical solution of the time-fractional fisher equation is formed and examined. The given non-linear partial differential equation through substitution is converted into a linear partial differential equation through substitution, using Taylor's series expansion. The time-fractional derivative is approximated in Caputo's sense while the space dimension is calculated using a new extended cubic B-spline. The proposed numerical technique is
