In this paper, we consider \(\eta\) -Ricci soliton on K-contact manifold. First, we prove that a K-contact metric representing an \(\eta\) -Ricci soliton is either Einstein, or D-homothetically fixed \(\eta\) -Einstein provided the Ricci operator Q commutes with \(\varphi\) . Next, we prove that a compact \(\eta\) -Ricci soliton ( \(g,V,\lambda , \mu\) ) on a K-contact manifold \(M^{2n+1}\) is \(\eta\) -Einstein (trivial) with Killing potential vector field. Finally, a couple of results are proved on contact metric manifold admitting \(\eta\) -Ricci soliton when its non-zero potential vector field is parallel with the Reeb vector field.
