The 1976–77 FIBA European Champions Cup was the 20th edition of the European top-tier level professional basketball club competition FIBA European Champions Cup (now called EuroLeague).

The Final was held at the Pionir Hall, in Belgrade, Yugoslavia, on April 7, 1977.

Maccabi Elite Tel Aviv defeated Mobilgirgi Varese, by a score of 78–77.

*Egyptian team Al-Gezira from Cairo was drawn into this group, but withdrew from the competition.
