Nygammal vals was the Swedish entry at the Eurovision Song Contest 1966 in Luxembourg performed by Lill Lindfors and Svante Thuresson. In the final, it was performed tenth, following Austria and preceding Spain. At the close of voting, it finished second with 16 points, making it Sweden's best showing in the Contest until ABBA won with "Waterloo" eight years later. Lill would go on to host the 1985 contest in Gothenburg as a result of her success.
