Eirik Wilhelm Wangberg (født 19. januar 1944) er en norsk plateprodusent, lydmann, musiker og låtskriver bosatt i Los Angeles. På begynnelsen av 60-tallet var han bassist i det norske The Cool Cats før han startet bandet Eirik Wangberg with The Noisemen. Etterhvert flyttet han til USA hvor han har jobbet som produsent og lydmann for flere internasjonale artister og deltatt på en rekke innspillinger som har toppet salgslistene. Blant artistene han har samarbeidet med er Paul McCartney, Diana Ross, John Travolta, The Beach Boys, Jimi Hendrix, Michael Jackson, The Mamas and the Papas, Janis Joplin og Carole King.
Wangberg ble tildelt bransjepris som plateprodusent under Spellemannprisen 1983.
Ram Wangberg går under tilnavnet Eirik the Norwegian, som han fikk av Paul McCartney i forbindelse med at han mikset albumet Ram av Paul & Linda McCartney (1971).
Han står oppført som «Mixing Engineer» på albumet, og spilte en svært viktig rolle da albumet ble laget. I forordet til Wangbergs selvbiografi Mitt liv blant stjerner skriver Paul McCartney følgende:
«Eirik played an important role when I was going to release RAM, my first full production solo album after The Beatles. His work in general, and many suggestions when recording overdubs and mixing the songs resulted in complete confidence, in him. For instance, from the finished recordings I let him choose the ones to be included on the album and to sequence them, something I always do myself.»Eirik Wangberg (i samarbeid med Stein Slettebakk Wangen): Mitt liv blant stjerner, Libretto Forlag 2015, side 7.
