Kehä III ("ring three", National road 50; or ; or ) is an important highway in Southern Finlandmarker. It is the outermost of the three beltways in the Helsinki region, and the first one to be built. It lies across the four Finnish municipalities of Kirkkonummimarker, Espoomarker, Vantaamarker and Helsinkimarker. Shaped like an arch, the road is long, of which only a very small fraction passes within the borders of Helsinki itself.

Work on Kehä III started in 1962, on the base of an existing road. The construction was finished in 1972, initially with only one lane per direction. Most of the Ring has since been expanded to at least two lanes per direction, although the western-most end is still one-lane per direction in places.

The most recent construction work has been extensive renovation on its busiest stretch in Vantaa, where several interchanges have been built or improved, and lanes added. Industrial development along the road has introduced higher volumes of heavy traffic.

The European route E18 is routed through Kehä III, bypassing central Helsinki.

The beginning was constructed between 1962 and 1964 from Bemböle to Länsisalmi and the continuation to Jorvas was completed in 1965. Originally, each road was two lanes wide. The amount of traffic grew considerably over time and as a result the original intersections with Helsinki's exit roads became dangerous. Therefore, all intersections with the city exits had been rebuilt as merging loops by the beginning of the 1970s. The road has undergone almost continual modification and widening throughout its existence as traffic has increased in the region.

In the mid-1970s, the road between Tikkurilamarker and Helsinki-Vantaa Airportmarker was renovated and 10 years later the road was expanded to four lanes up to Vihdintie. At the end of the 1980s, the road was extended to Muurala and then once again one kilometer farther to the west. This same stretch was rebuilt shortly afterwards when it was expanded to four lanes up through Gumböle during the 1990s. Throughout the 1980s, stretches of Kehä III were completed to the Lahtimarker motorway and in the 1990s to the Porvoo motorway. The last stretches of Kehä III were completed in 2006 and 2007 to Vuosaari Harbourmarker. At the start of 2000s major improvements were made to the heavily used stretch from Tikkurila to Helsinki-Vantaa Airport: the road was widened to 6 lanes and Tuusulamarker motorway's intersection was rebuilt as a large system connection.

When the road was originally built, it was simply called the "Ring road", but the planning of the other two major roads caused confusion. Therefore it was called Kehä III from the 1970s onward.
