Stream of Passion is a Dutch progressive metal band with symphonic and gothic influences founded by guitarist and composer Arjen Anthony Lucassen and Mexican singer, violinist, and lyricist Marcela Bovio. They have released four studio albums.

In 2007, Lucassen left the band to continue on his own as he had originally planned, together with his girlfriend guitarist Lori Linstruth, and keyboardist Alejandro Millán; Bovio, her boyfriend (later husband) and bassist Johan van Stratum and producer Joost van den Broek handling the composition duties afterwards. After keeping a steady line-up since 2009, the band announced in April 2016 that they would disband, wanting to end on a high note rather than letting the interest and inspiration fade away, after a live album entitled Memento and a final show on 28 December 2016.
