The oblique lattice is one of the five two-dimensional Bravais lattice types.{{Cite web|last=Rana|first=Farhan|title=Lattices in 1D, 2D, and 3D|url=https://courses.cit.cornell.edu/ece407/Lectures/handout4.pdf|url-status=live|archive-url=https://web.archive.org/web/20201218214110/https://courses.cit.cornell.edu/ece407/Lectures/handout4.pdf|archive-date=2020-12-18|website=Cornell University}} The symmetry category of the lattice is wallpaper group p2. The primitive translation vectors of the oblique lattice form an angle other than 90° and are of unequal lengths.
