- the quality or condition of being strange.
- Physics. a quantum number assigned the value −1 for one kind of quark, +1 for its antiquark, and 0 for all other quarks; the strangeness of a hadron is the sum of the values for the strangeness of its constituent quarks and antiquarks. Symbol: S
Compare strange quark.

- the state or quality of being strange
- physics a property of certain elementary particles, characterized by a quantum number (strangeness number) conserved in strong and electromagnetic but not in weak interactions. It is associated with the presence of strange quarks

- The property of containing a strange quark or antiquark. Strangeness is expressed in terms of an integer quantum number, -1 for each strange quark and +1 for each strange antiquark. Hadrons that possess strangeness are called strange. The total strangeness of a quantum system is unchanged by decay processes involving the strong or electromagnetic forces; however, decay through the weak force can change the total strangeness of the system.
