In the mathematical discipline of graph theory the Tutte theorem, named after William Thomas Tutte, is a characterization of finite graphs with perfect matchings. It is a generalization of Hall's marriage theorem from bipartite to arbitrary graphs. It is a special case of the Tutte–Berge formula.

The proof builds an edge-maximal graph G' containing G that does not contain a 1-factor, and finds a set S that violates Tutte's condition in G'. Building such a G' would require a decision procedure that answers …
