- A major rule change in 1966 introduced the national-language requirement, implemented after Sweden’s 1965 English-language entry.
- Austria won with Udo Jürgens’s “Merci, Chérie”, the first winning song performed in German, and Jürgens’s third consecutive participation; Austria would not win again until 2014.
- The Netherlands’ Milly Scott became the contest’s first Black performer.
- Controversy arose when Italy’s Domenico Modugno changed his arrangement late and exceeded the time limit; after threatening withdrawal, he was allowed to perform with his own small ensemble instead of the orchestra.
