We give a list of 28 theorems which are all equivalent to Farkas's Lemma. This list includes Gordan's Theorem, Stiemke's Theorem (Fundamental Theorem of Asset Pricing), Slater's Theorem, Gale's Theorem, Tucker's Theorem, Ville's Theorem (von Neumann's Theorem of the Alternative), von Neumann's Minimax Theorem for matrix games, Motzkin's Theorem, the Strong Duality Theorem in linear programming, and Broyden's Theorem. For convenience of exposition, we also mention three versions of Separating Hyperplane Theorems which are equivalent to Farkas's Lemma.
