The deadline for nations to confirm their participation at the 2008 Olympic Games was 31 May 2008. In light of the confirmations from the National Olympic Committees, the latest list of qualified nations per discipline (team and individual) attending the 2008 Olympic Games is presented below.
Cancellations in both Dressage and Eventing have meant that new quota spaces have been reallocated. Two of these spaces will go to countries that were not originally part of the qualified nations, namely to the Czech Republic with one Eventing rider and Portugal with one Dressage Rider (their participation is still subject to confirmation from the NOC and NF). Furthermore, France and Russia are now represented by Dressage teams following the reallocation of quota spaces, while Poland, in addition to their two Eventing riders, is now represented by a Dressage rider.
The tally for nations qualified to participate has thus risen to 43, a record for equestrian sports at the Olympic Games.
