Seal of Montgomery County, Maryland, in use since at least 1987. Not to be confused with the emblem. Although the seal is official and current, it is however rarely seen outside of some limited internal county use. For promotional and more public purposes, the county prefers to use the more prominent "Montgomery County emblem".
