List of county routes in Putnam County, New York

Most of the county road numbers, which are all two-digits, are signed with the standard yellow-on-blue pentagon route marker specified by the Manual on Uniform Traffic Control Devices (sign M1–6), which is also used in other counties throughout the state.

This is reflected in local vernacular, as most residents refer to the county roads by name and not by number.

The three villages in Putnam County are included with their respective towns.

On a town level, the numbers are assigned in a roughly west-to-east and south-to-north fashion.

The presence of skipped numbers in the order (such as CR 31) implies that there are a few decommissioned roads, but some (like CR 52) were likely skipped intentionally to avoid confusion with state routes in the county.
