"Nygammal vals" ("New, yet familiar, waltz") was the Swedish entry to the Eurovision Song Contest 1966 in Luxembourg, Luxembourg. It was sung in Swedish by Lill Lindfors and Svante Thuresson, composed by Bengt Arne Wallin and written by Björn Lindroth. In Luxembourg they were joined on stage by the American jazz musician Sahib Shihab on flute.
Performing 10th on the night, following Austria's Udo Jürgens singing "Merci Chérie" and preceding Spain's Raphael with "Yo soy aquél", it finished 2nd with 16 points in a field of 18, making it Sweden's best showing in the Contest until ABBA won with "Waterloo" in 1974.
It was succeeded as Swedish representative at the 1967 contest by Östen Warnerbring with "Som en dröm"
