HD 11964d is an extrasolar planet approximately 111 light-years away in the constellation of Cetus. The planet was the third planet discovered around the yellow subgiant star HD 11964, but is the second planet in order of distance from the star. The planet is 70% the mass of Saturn, but since inclination is not known, only minimum mass is known. The orbit is extremely eccentric at the average distance of 1.13 AU, taking 360 days to complete its orbit.

The planet was discovered by using a new technique called Bayesian Kepler periodogram in September 2007 by P.C. Gregory. This technique finds trends in wobbling of stars more easier than other methods, and hence easier to detect multiple planetary systems.
