Let $G$ be a connected graph with vertex set $V(G)$. The degree resistance distance of $G$ is defined as $D_R(G) = \sum_{\{u, v\} \subseteq V(G)} [d(u)+d(v)] R(u,v)$, where $d(u)$ is the degree of vertex $u$, and $R(u,v)$ denotes the resistance distance between $u$ and $v$. In this paper, we characterize $n$-vertex unicyclic graphs having minimum and second minimum degree resistance distance.
