The A6 is a national road in Latvia, connecting Riga to the Belarusian border at Pāternieki.

Currently the A6 has two lanes in each direction between Riga and Ogre and between Nīcgale and Daugavpils, with other parts having just a single carriageway.

The current speed limit in winter is 90 kilometres per hour (56 mph), but in summer the dual carriageway parts are raised to 100 kilometres per hour (62 mph).

Since 2013 a shorter route has replaced the Salaspils-Koknese section of A6 (numbered as P80), mainly built for transit traffic.

It was planned to be complete by 2012, but due to economical reasons the works were delayed and were finished in 2013.
