      An integral domain $R$ is called a locally almost perfect domain provided that $R_{\frak m}$ is an almost perfect domain for any maximal ideal ${\frak m}$ of $R$. In this paper, we give several characterizations of locally almost perfect domains in terms of locally perfect rings, almost projective modules, weak-injective modules, almost strongly flat modules and strongly Matlis cotorsion modules.
