Pole may refer to:

Astronomy[edit]

  • Celestial pole, the projection of the planet Earth's axis of rotation onto the celestial sphere; also applies to the axis of rotation of other planets
  • Pole star, a visible star that is approximately aligned with the Earth's axis of rotation
  • Orbital pole, the projection of the line perpendicular to planet Earth's orbit onto the celestial sphere; also applies to the orbit of other planets
  • Poles of astronomical bodies, concepts analogous to the Earth's geographic and magnetic poles on other planets and Solar System bodies

Cylindrical objects[edit]

A solid cylindrical object or column with its length greater than its diameter, for example:

  • Asherah pole, a sacred tree or pole that stood near Canaanite religious locations to honor the Ugaritic mother-goddess Asherah, consort of El

  • Fireman's pole, wooden pole or a metal tube or pipe installed between floors in fire stations
  • Flagpole (structure), metal pole from which a flag is hung
  • Lamppost, a raised source of light on the edge of a road
  • Totem pole, monumental sculptures carved from great trees
  • Utility pole, also called a telephone pole, telegraph pole or power pole, a pole that carries utility wires
  • Poles used in sporting and other activities:
    • Dance pole, a pole used for pole dancing
    • Danish pole, a circus prop
    • Festivus pole, a pole used in the celebration of Festivus that is traditionally made of aluminium
    • Fishing pole, tool used to catch fish
    • Foul pole, used in the sport of baseball to distinguish foul balls from fair balls hit into the outfield
    • Maypole, a tall wooden pole with ornaments, like ribbons, that is danced around
    • Pole bending, a rodeo event that involves riding a horse around six poles arranged in a line
    • Pole position, in motorsport, the position at the front of the starting grid (originally marked with a pole)
    • Pole-sitting pole, a pole used for pole sitting, which is the practice of sitting on a pole for extended lengths of time
    • Pole vaulting pole, a pole used for pole vaulting
    • Pole weapon, combat weapon in which the main fighting part of the weapon is placed on the end of a long shaft, typically of wood
    • Ski pole, a pole used by skiers to improve balance, speed and acceleration
    • Spinnaker pole, a spar used in sailboats to help support and control a variety of headsails, particularly the spinnaker
    • Trekking pole, also called hiking sticks or hiking poles, a pole used for hiking

Geography and places[edit]

  • Geographical pole, either of two fixed points on the surface of a spinning body or planet, at 90 degrees from the equator, based on the axis around which a body spins
    • North Pole, the northernmost point on the surface of the Earth, where the Earth's axis of rotation intersects the Earth's surface
    • Polar circle, either of two circles of latitude marking the extreme southerly points (northern hemisphere) or northerly points (southern hemisphere) at which the sun may remain above or below the horizon for 24 continuous hours at some point during the year
    • Polar region, the region within the polar circles, referred to as the Arctic and Antarctic
    • South Pole, the southernmost point on the surface of the Earth, where the Earth's axis of rotation intersects the Earth's surface
  • Magnetic poles of astronomical bodies
    • North Magnetic Pole, the shifting point on the Earth to which the "north" end of a dipole magnet points
    • South Magnetic Pole, the shifting point on the Earth to which the "south" end of a dipole magnet points
  • Mount Everest, the third "top" of the Earth
  • Pole of inaccessibility, a location that is the most challenging to reach owing to its remoteness from geographical features which could provide access
  • Pole, Lubusz Voivodeship (west Poland)
  • Pole in North East of Botswana
  • The West Pole, Texas
  • Hanbury Manor, Ware, Hertfordshire, formerly known as "Poles"

Fictional[edit]

  • "East Pole" and "West Pole", imaginary locations; Christopher Robin tells Winnie-the-Pooh that these exist as well but "people don't like talking about them"

Science, technology, and mathematics[edit]

  • One "half" of a dipole
  • Pole, term used in electrical circuits used to describe switch contact variations
  • Pole (unit of length), a unit of length equal to 512 yards, or 1612 feet (5.0292 metres): also known as a rod, or a perch
  • Landau pole, the energy scale where a coupling constant of a quantum field theory becomes infinite
  • Magnetic pole, one of the two ends of a magnet
  • Monopole (disambiguation)
    • Magnetic monopole, a hypothetical particle that may be loosely described as a magnet with only one pole
    • Monopole (mathematics), a connection over a principal bundle G with a section (the Higgs field) of the associated adjoint bundle
    • Monopole (wine), an appellation controlled by a single winery
    • Monopole antenna, a radio antenna that replaces half of a dipole antenna with a ground plane at right-angles to the remaining half
  • Mathematics
  • Mechanics
    • Pole (Mohr's circle), or origin of planes, a point located in Mohr's circle; considering the Mohr circle of a material point in a continuous body (e.g., a rock mass, soil mass, concrete column, bone, etc.), any straight line drawn from the pole intersects the Mohr circle at a point with coordinates representing the state of stress on an imaginary plane, passing through the material point, having the same inclination (parallel) in space as that line in the Mohr circle space.
  • Meteorology
    • Polar climate, the climate of the polar regions, characterized by a lack of warm summers
    • Polar front, the boundary region between the polar cell and the Ferrel cell in each hemisphere
  • Pole figure, a method for representing crystal symmetry

Psychology and biology[edit]

  • Anterior and posterior poles, surface vertices of the eye's lens
  • Fetal pole, a thickening on the margin of the yolk sac of a fetus during pregnancy
  • Pole of kidney
  • POLE, a DNA polymerase epsilon catalytic subunit – enzyme that in humans is encoded by the POLE gene
  • Cell (biology), either extremity of the main axis of a nucleus, cell, or organism. Important structures situated close to such extremities have also been regarded as poles (e.g. animal cell centrosomes).
  • East Pole–West Pole Divide, an intellectual schism between researchers in the fields of cognitive psychology and cognitive neuroscience
