In Greek mythology, the oak is the tree sacred to Zeus, king of the gods. In Zeus's oracle in Dodona, Epirus, the sacred oak was the centerpiece of the precinct, and the priests would divine the pronouncements of the god by interpreting the rustling of the oak's leaves.
In Baltic and Slavic mythology, the oak is the sacred tree of Latvian Prkons, Lithuanian Perknas, Prussian Perkns and Slavic Perun, the god of thunder and one of the most important deities in the Baltic and Slavic pantheons.
In Celtic polytheism, the name of the oak tree was part of the Proto-Celtic word for 'druid': *derwo-weyd- > *druwid- ; however, Proto-Celtic *derwo- (and *dru-) can also be adjectives for 'strong' and 'firm', so Ranko Matasovic interprets that *druwid- may mean 'strong knowledge'. As in other Indo-European faiths, Taranis, being a thunder god, was associated with the oak tree. The Indo-Europeans worshiped the oak and connected it with a thunder or lightning god; "tree" and drus may also be cognate with "Druid," the Celtic priest to whom the oak was sacred. There has even been a study that shows that oaks are more likely to be struck by lightning than any other tree of the same height.
In Norse mythology, the oak was sacred to the thunder god, Thor. Thor's Oak was a sacred tree of the Germanic Chatti tribe.
In the Bible, the oak tree at Shechem is the site where Jacob buries the foreign gods of his people (Gen. 35:4) .

Absalom's long hair (2 Samuel 18:9) gets caught in an oak tree, and allows Joab to kill him.

Linnaeus described only five species of oak from eastern North America, based on general leaf form. These were white oak, Quercus alba; chestnut oak, Q. montana; red oak, Q. rubra; willow oak Q. phellos; and water oak, Q. nigra. Because he was dealing with confusing leaf forms, the Q. montana and Q. rubra specimens actually included mixed foliage of more than one species.
