Let $G$ be a graph of order $n$ and $\lambda ( G) $ the spectral radius of its adjacency matrix. We extend some recent results on sufficient conditions for Hamiltonian paths and cycles in $G$. One of the main results of the paper is the following theorem: \endgraf Let $k\geq 2,$ $n\geq k^{3}+k+4,$ and let $G$ be a graph of order $n$, with minimum degree $\delta (G) \geq k.$ If \[ \lambda ( G) \geq n-k-1, \] then $G$ has a Hamiltonian cycle, unless $G=K_{1}\vee (K_{n-k-1}+K_{k})$ or $G=K_{k}\vee (K_{n-2k}+\bar {K}_{k}).$
