The Red Cow Interchange is a major road junction in Ireland, and potentially the most well-known in the country. It's where the M50 bypass of Dublin meets the N7 towards Cork, Waterford and Limerick.

It was constructed in 1990 with the opening of the M50 in the area, and named after the townland of the same name. A Red Cow Inn is shown on the site on 19th century maps. The junction was made more unusual with the opening the Luas red tram system, which crossed the motorway sliproads with traffic lights.

Construction of the Red Cow Interchange improvements in January 2007.

The junction was originally a simple roundabout interchange, but as the M50 was extended and the N7 / N8 / N9 routes gradually improved, it suffered more and more from being a notorious bottleneck. The Luas park and ride positioned at the junction became an important transport interchange, too. There were now three lanes of N7 meeting the roundabout, and it was a regular feature of local traffic reports.

Work started on the junction improvements around May 2006 and a few initial freeflow links opened in October 2007. Construction continued on the junction during 2007 and 2008, and by early 2009 most of the work was complete. The new junction is largely free-flow, and stands out for its complex arrangements of flyovers, loops and the tramway.

Despite the impression given by the layout of the junction, since the M50 opened this has not been the main route into Dublin. The N7 was shortened so that it began here, and traffic heading towards the city was told to join the M50 to Palmerstown. Signage for "City Centre" returned with the junction upgrade.

As is the case with other landmarks in Ireland, it has been given an unofficial slang name of the "Mad Cow" Interchange, a particularly popular moniker during the junction improvements. Despite the new road layout, the junction does still suffer from congestion, primarily due to vehicles braking for the loops.
