* Hilbert's Theorem 90, an important result on cyclic extensions of fields that leads to Kummer theory
* Hilbert's basis theorem, in commutative algebra, stating every ideal in the ring of multivariate polynomials over a Noetherian ring is finitely generated
* Hilbert's finiteness theorem, in invariant theory, stating that the ring of invariants of a reductive group is finitely generated
* Hilbert's irreducibility theorem, in number theory, concerning irreducible polynomials
* Hilbert's Nullstellensatz, the basis of algebraic geometry, establishing a fundamental relationship between geometry and algebra
* Hilbert's syzygy theorem, a result of commutative algebra in connection with the syzygy problem of invariant theory
