R4 expressway (Slovak: Rýchlostná cesta R4) is an expressway in the north–south direction in eastern Slovakia. Initially planned to be completed in 2023^[1], the completed 130 kilometres (81 mi) long expressway will connect the state border of Poland to the border with Hungary, passing Svidník, Prešov and Košice.

On the Polish side, the R4 will be connected to the S19 expressway; on the Hungarian side, to the M30 motorway. The section between Prešov and Košické Oľšany is shared with D1, and sections between Košické Oľšany and Haniska with R2. The road is part of the proposed Via Carpatia route^[2].

From the total length of 73.9 km (excluding shared sections), these sections are in operation:

• 4.6 km Svidník bypass (two-lane) ^[3]
• 14.2 km Haniska - Milhosť^[3]
