In [[theoretical physics]], a '''supermultiplet''' is a [[group representation|representation]] of a [[supersymmetry algebra]], possibly with [[extended supersymmetry]].

Then a '''superfield''' is a field on [[superspace]] which is valued in such a representation. Naïvely, or when considering flat superspace, a superfield can simply be viewed as a function on superspace. Formally, it is a [[section (fiber bundle)|section]] of an [[associated vector bundle|associated supermultiplet bundle]].

Phenomenologically, superfields are used to describe [[particles]]. It is a feature of supersymmetric field theories that particles form pairs, called [[superpartner]]s where [[bosons]] are paired with [[fermions]].

These supersymmetric fields are used to build supersymmetric [[quantum field theories]], where the fields are promoted to [[Hermitian operator|operator]]s.
