  We construct a solvable deformation of two-dimensional theories with $(2,2)$
supersymmetry using an irrelevant operator which is a bilinear in the
supercurrents. This supercurrent-squared operator is manifestly supersymmetric,
and equivalent to $T\bar{T}$ after using conservation laws. As illustrative
examples, we deform theories involving a single $(2,2)$ chiral superfield. We
show that the deformed free theory is on-shell equivalent to the $(2,2)$
Nambu-Goto action. At the classical level, models with a superpotential exhibit
more surprising behavior: the deformed theory exhibits poles in the physical
potential which modify the vacuum structure. This suggests that irrelevant
deformations of $T\overline{T}$ type might also affect infrared physics.
