  In this article, we are reporting for the first time the existence of
gravastar configurations in the framework of K(R,T)-gravity, which can be
treated as an alternative to a black hole (Mazur and Mottola). This strengthens
how much this new gravity theory may be physically demanding to the gravity
community in the near future. We first develop the gravastar field equations
for a generic K(R,T) functional and then we study four different models within
this theory. We find that the solutions for the interior region are regular
everywhere regardless of the exact form of the K(R,T) functional. The solutions
for the shell region indicate that two of the four models subjected to the
study are physically feasible. In addition, the junction conditions are
considered at each interface by using the Lanczos equations that yield the
surface density and pressure at the thin shell. We investigate various
characteristics of the gravastar structure such as the proper length, energy,
and entropy of the spherical distribution.
