Rheinquelle lighthouse, Mountain lighthouse at Oberalppass, Switzerland.

Rheinquelle lighthouse is a ten-metre tower on Oberalppass in the Swiss canton of Grisons, built in 2010 near the source of the Rhine. It is a replica of the former lower light of Hoek van Holland, which marked the Rhine's mouth on the North Sea for 70 years and has stood in the Maritiem Museum in Rotterdam since 1990.

The ten-metre tower was erected in 2010 as part of a tourism marketing campaign for the Oberalppass holiday region. It is a replica of the former Hoek van Holland lower light, which marked the Rhine's mouth in the North Sea for 70 years and has stood in the Maritiem Museum in Rotterdam since 1990. Since 2015 the Stiftung Leuchtturm Rheinquelle in Sedrun has run and maintained it.

The tower is a replica of the former Hoek van Holland low light, which marked the Rhine's mouth for 70 years and has stood in the Maritiem Museum in Rotterdam since 1990. Each year the Stiftung Leuchtturm Rheinquelle names a celebrity as honorary keeper, among them Nik Hartmann in 2019.

The tower stands on Oberalppass in the Grisons, at 2046 metres, beside the road that crosses the pass and near the spring taken as the source of the Rhine. The pass is reached by road and by the Matterhorn Gotthard railway, whose Oberalppass station lies close by. The tower is a replica of the old Hoek van Holland lower light and is looked after by the Stiftung Leuchtturm Rheinquelle in Sedrun.
