This page documents radio frequencies used by Missouri State Parks, a division of the Missouri Department of Natural Resources (MoDNR). These frequencies support day‑to‑day operations at Missouri’s state parks and state historic sites, including park rangers, campground hosts, park offices, and maintenance staff.

While Missouri State Parks operates independently from the Missouri Department of Conservation (MDC), some facilities—such as Missouri’s trout parks—are jointly managed, with State Parks overseeing land, campgrounds, and visitor services, and MDC operating fish hatcheries and fisheries programs. This shared geography can result in nearby or overlapping radio activity, but the systems remain separate.

The majority of radio traffic heard on these frequencies involves campground operations, maintenance activities, ranger coordination, and park or historic site offices, rather than wildlife enforcement.

DNR Park Rangers are law enforcement at State Parks. -- They have limited-or no-access to the Campground channels.  Most of their Law enforcement communications are handled through the Missouri State Highway Patrol troop responsible for the park’s location."
