  In this paper, we build a thin-shell gravastar model within a noncommutative
BTZ geometry. For this, we consider a noncommutative BTZ metric in the inner
region and a geometry associated with a BTZ solution in the outer region,
joined by the generalized join technique. After investigating the inner
spacetime, surface and outer spacetime, we observe that there is a surface
energy density and surface pressure, such as to make gravastar stable. This
effect persists even when the cosmological constant is zero. Besides, we found
a bound for the noncommutativity parameter. In addition, we examine the
thermodynamics of the noncommutative BTZ black hole in Schwarzschildtype form
in three-dimensional spacetime. We also check the stability condition by
calculating the specific heat capacity.
