European route E55 is an E-route. It starts in southern Sweden, crosses the Øresund strait to Denmark, and passes through more water (the western Baltic Sea) to reach continental Europe on Rostock, Germany. Thence it continues further southward on land through Germany and into the Czech Republic, Austria, and Italy. Finally, it passes through the Ionian Sea to serve western Greece.

The route passes through the following cities in order:

Helsingborg ... Helsingør – Copenhagen – Køge – Vordingborg – Nykøbing Falster – Gedser ... Rostock – Berlin – Lübbenau – Dresden – Ústí nad Labem – Prague – Tábor – Linz – Salzburg – Villach – Tarvisio – Udine – Palmanova – Venice – Ravenna – Cesena – Rimini – Fano – Ancona – Pescara – Canosa di Puglia – Bari – Brindisi ... Igoumenitsa – Preveza – Rio – Patras – Pyrgos – Kalamata.

From Helsingborg, the route was supposed to continue northward through Sweden and into Finland, but a decision was made to keep the E4 designation in Sweden, formerly used for a European route from Lisbon to Helsinki. The E55 is not and has not been signposted in Sweden. Since 2018, the E55 is not signposted between Helsingør and Køge in Denmark, but is signposted south of Køge.
