This article is about the Class III road numbered C200 maintained by DfI Roads.

The C200 is a lengthy C road running closely alongside the Armagh/Monaghan border for much of its length. It starts at a roundabout on the A29 in Keady and heads south. After passing through Darkley a crossroads is met and the road continues by turning off to the south. Soon the road swings south east and comes to a TOTSO with the C203 with the road continuing its journey south east. Before long the road comes to a halt on the A25 and continues from a junction immediately east of the border. From here the road follows the border south very closely, but gradually it does move further away. On the approach to another TOTSO, the road meets the C223 which heads in the direction of Cullyhanna. After the TOTSO, the road soon ends on the B135 after over 20 kilometres.
