The Alekhine Memorial was a recurring chess tournament, organized in different cities and irregular intervals, honoring the former world chess champion Alexander Alekhine.
The Alekhine Memorial tournaments have no numbering (technically it is not a series), sometimes it is thus unclear whether or not an event can be regarded as an Alekhine Memorial (as for instance at Moscow in 1959 and the following Moscow Central Chess Club International tournaments).
Immediately after Alekhine's death, Erich Eliskases won at Rio de Janeiro in 1946 the first Alekhine Memorial ever held.
