A family of new algorithms is given for evaluating the first <italic>m</italic> derivatives of a polynomial. In particular, it is shown that all derivatives may be evaluated in 3<italic>n</italic> - 2 multiplications. The best previous result required 1/2<italic>n</italic>(<italic>n</italic> + 1) multiplications. Some optimality results are presented.
