Proposition may refer to:
In logic, mathematics, and philosophy
- Proposition (philosophy), meaning one of:
- the "content" or "meaning" of a meaningful declarative sentence
- the pattern of symbols, marks, or sounds that make up a meaningful declarative sentence
- whatever entities are true or false
- As a special case, textbooks often, and papers sometimes, label an assertion which is provably true, but not important enough to be a theorem, a proposition. Normally this is part of a numerical reference system (Proposition 3.2, Lemma 3.3, Theorem 3.4); see the dictionary definition of "Proposition".
- Propositional calculus (also propositional logic or sentential calculus) - a formal system in which formulae representing propositional formulas can be formed.
- Propositional formula - a type of syntactic formula which is well formed and has a truth value; i.e., an assertion formulated in such a way that it may be proven true or false
