Dag Vag is a Swedish band formed in 1978.

The lead singer was Per Odeltorp (1948–2012), popularly known as Stig Vig.

Their early punk sound became, after a while, increasingly more reggae-like.

The band referred to it as "transcontinental rock-reggae".

Dag Vag sometimes toured with Swedish punk band Ebba Grön and made a cameo in their documentary film Ebba the Movie.
