M09 is a Ukrainian international highway (M-highway) which is part of the Warsaw - Lviv route. It starts as a split-off from M06 coming from Lviv, then turning north it heads towards the border with Poland. The highway terminates at the border checkpoint Rava-Ruska. Across the Polish border it continues as the regional road 17.
This route belonged until 1918 to the Austrian crown land of Galicia and was called the Żółkiewer Reichsstraße.
