We extend the concept of conventional multiferroicity - where ferroelectric and ferromagnetic orders coexist - to include multipolar degrees of freedom. Specifically, we explore how this phenomenon emerges in 4d2/5d2 Mott insulators with strong spin-orbit and Hund's couplings. Our study uncovers the origin of magnetic multipolar interactions in these systems and demonstrates that a combination of quadrupolar and octupolar magnetic order can simultaneously induce both electrical quadrupolar moments and ferroelectric polarization. By expanding the multiferroic framework to higher-order multipoles, we reveal the possibility of coexisting multipolar orders of different or same ranks, paving the way for different functional properties in a large class of strongly correlated materials.
