Ronald Reagan is the only U.S. president who was born in Illinois, in Tampico on February 6, 1911.

Illinois is closely associated with several presidents—Abraham Lincoln, Ulysses S. Grant, Barack Obama, and Ronald Reagan—but Lincoln, Grant, and Obama were born in other states and only later became politically tied to Illinois. Ronald Reagan stands out because his actual birthplace is in Illinois, which is why he is recognized as the only U.S. president born there.
