The 26th Chess Olympiad (, I 26i Skakistikí Olympiáda), organized by FIDE and comprising an open and a women's tournament, as well as several other events designed to promote the game of chess, took place between November 18 and December 5, 1984, in Thessaloniki, Greece. In the home country of the Olympic movement, it was business as usual. The Soviet Union, led by Beliavsky, won their third consecutive gold medals (and 15th in total), well ahead of England (helped by a Nunn in top form) and the United States. This dominance happened even in the absence of Karpov and Kasparov who were in the midst of their marathon match. In fact, for the first time in Olympic history, the Soviet team didn't feature a single world champion – past, present or future. The only champion present in Thessaloniki was Boris Spassky who had defected and now represented France. His performance helped the French team to an unprecedented 7th-place finish, even though he drew 12 of his 14 games – an Olympic record. After the successful 26th Olympiad in Thessaloniki in 1984, FIDE agreed to hold every other Olympiad (the ones in Olympic years) in the home country of the Olympic movement - provided the Greek Chess Federation and government could provide the necessary funding. This was only the case once, in 1986; after that the Olympiad went back to a new host city every two years.

Open event

There were 87 nations playing in a 14-round Swiss system tournament. To make for an even number of teams, the Greek hosts also fielded a "B" team. In the event of a draw, the tie-break was decided first by using the Buchholz system, then by match points. ! # !! Country !! Players !! Average rating !! Points ! # !! Country !! Average rating !!

Women's event

50 nations took part, and with the Greek hosts also fielding a "B" side, the total number of teams came to 51. In the event of a draw, the tie-break was decided first by using the Buchholz system, then by match points. Like the open event, the women's tournament was dominated by the Soviet Union, captained by world champion Chiburdanidze, who won the gold medals by an impressive 5½ points. Bulgaria and Romania took silver and bronze, respectively. ! # !! Country !! Players !! Average rating !! Points ! # !! Country !! Average rating !! Points !! Buchholz
