We define a new class of a rank-3 matroid called a trilateral matroid. When defined, the ground set of such a matroid consists of the points of an n3-configuration, and its bases are the point triples corresponding to non-trilaterals within the configuration. We characterize which n3-configurations induce trilateral matroids and provide several examples.
