Be2gether or B2G is the second largest (after Positivus festivalis) annual music and arts festival in Baltic countries. Established in 2007, it takes place in Norviliškės, Lithuania, just a few meters from the border with Belarus. In 2007 attendance was estimated at 7,000–8,000, while it increased to 12,000 in 2008.

Be2gether represents different musical flavors, including rock, electronic, world and alternative music. The festival invites mostly international bands. In addition to musical performances, the festival offers other activities, including craft studios, cinema in the open air, sport games, music and dance lessons, sculpture park. The children are offered daycare with their own activities. In 2009, Be2gether one of the events of "Vilnius - European Capital of Culture". Part of the money gathered during the festival is dedicated for humanitarian aid.

Be2gether was created with a slogan Music Opens Borders to unite people, despite the differences in their culture, nationality, age or social position. To underscore this goal, the festival is held in the so-called Dieveniškės panhandle: Lithuanian territory surrounded by Belarus on three sides. The area is remote and is difficult to reach, as travel across border is restricted as Lithuania is a member of the European Union and Belarus is not. In 2008, Belarusians could receive the needed visas without a fee if they traveled to the festival. Due to festival's proximity to the state border, special security measures have to be undertaken to prevent people from inadvertently crossing the border. The festival is situated in the historic Vilnius Region, inhabited by peoples of Lithuanian, Polish, Belarusian, Russian decent. The Renaissance Norviliškės Castle reminds the visitors of shared history under the Grand Duchy of Lithuania.
