The Olympic oaks, informally called Hitler oaks, are English oak trees that were given to gold medal winners of the 1936 Berlin Olympic Games. 130 gold medals and trees, which were year-old saplings, were awarded. Several have survived.

While the largest number of oaks were given to German athletes, who won the most medals, many are said^{[according to whom?]} to be planted near the stadium, though no record was kept, and they would be difficult to identify among the many oaks in the vicinity.^{[citation needed]}

The Netherlands has 2 Olympic oaks planted at the Olympic Stadium in Amsterdam.
