Quercus × deamii (or Quercus deamii), known as Deam's oak, is a naturally occurring hybrid of chinquapin oak (Quercus muehlenbergii) and burr oak (Quercus macrocarpa). It occurs sporadically where their ranges overlap in the eastern United States and eastern Canada.[2] It is named for self-taught botanist and state forester of Indiana Charles C. Deam, who had forwarded samples to William Trelease for description. It was originally though to be a cross of Q. alba and Q. macrocarpa.

Quercus × deamii is a forest tree with pale bark and a spreading crown of stout branches. The twigs and leaf undersides are short-hairy.[3]​

When the original tree was marked for felling, Deam managed to buy the 0.2 acres (0.08 ha) of land it stood on for the state. It is now the Deam Oak Monument Forest, at

As the name suggests, it does not produce acorns, a desirable trait in certain garden and landscaping applications.[6]
