The N32 road was a short national primary road in Ireland running from junction 3 on the M50, to the Malahide Road at Clare Hall. It was approximately in length.
Termed the "Northern Cross Route Extension" when it was designated in 1996, it was effectively a non-motorway addition to the M50. A short part of the route had motorway restrictions on it as it led to the M1-M50 interchange (and was confusingly signposted as both N32 and M50), as only motorway traffic can access both routes. In 2012, this section became a spur of the M50, with the rest of the route being renumbered as R139.
