Pore may refer to:

In animal biology and microbiology:

Sweat pore, an anatomical structure of the skin of humans (and other mammals) used for secretion of sebum
Canal pore, an anatomical structure that is part of the lateral line sense system of some aquatic organisms
An opening across both inner and outer bacterial membranes, a part of many Gram-negative bacterial secretion systems
One of the openings communicating with the skin surface at the terminus of lactiferous ducts in milk-producing mammals

In plant biology

Stoma, a small opening on a plant leaf used for gas exchange
An anatomical feature of the anther in some plant species, the opening through which pollen is released
A characteristic surface feature of porate pollen

Nuclear pore, a large protein complex that penetrates the nuclear envelope in eukaryotic cells
Ion channel pore; The ion-selective opening in the membrane of a eukaryotic cell formed by members of the ion channel family of proteins
A water-selective opening (water channel) in the membrane of a eukaryotic cell formed by assemblies of the protein aquaporin

In the physical sciences:

One of many small openings in a solid substance of any kind that contribute to the substance's porosity (typical usage in earth sciences, materials science and construction)
A small defect in the crystal structure that may arise during sintering to form solids from powders, including ceramics
