We study the dynamical stability of an additional, potentially habitableplanet in the HD 47186 planetary system. Two planets are currently known inthis system: a "hot Neptune" with a period of 4.08 days and a Saturn-massplanet with a period of 3.7 years. Here we consider the possibility that one ormore undetected planets exist between the two known planets and possibly withinthe habitable zone in this system. Given the relatively low masses of the knownplanets, additional planets could have masses $\lsim 10 \mearth$, and hence beterrestrial-like and further improving potential habitability. We perform$N$-body simulations to identify the stable zone between planets $b$ and $c$and find that much of the inner habitable zone can harbor a $10 \mearth$planet. With the current radial-velocity threshold of $\sim 1$ m/s, anadditional planet should be detectable if it lies at the inner edge of thehabitable zone at 0.8 AU. We also show that the stable zone could contain twoadditional planets of $10 \mearth$ each if their eccentricities are lower than$\sim 0.3$.
