De Boom Die Alles Zag (transl. The Tree That Saw It All) is a grey poplar (Populus × canescens) tree located in Bijlmermeer, Amsterdam, the Netherlands, that survived the crash of El Al Flight 1862 on 4 October 1992. Due to the eye-shaped patterns on its trunk, the tree was considered to be an eyewitness of the accident and its aftermath. An official memorial was built next to the tree, where the accident is commemorated every year on its anniversary. It is a part of a larger monument, Het Groeiend Monument (transl. The Growing Monument).

The tree lost a part of its roots during the clean-up of the soil, which made it necessary to support it with two cables attached to neighbouring trees. The soil under it was replaced in 2017 to stimulate root growth, which according to pulling tests four years later improved its condition, but the tree is still supported by the cables to prevent it from falling.
