Wigner distribution or Wigner function may refer to:

• Wigner quasiprobability distribution (what is most commonly intended by term "Wigner function"): a quasiprobability distribution used in quantum physics, also known at the Wigner-Ville distribution
• Wigner distribution function, used in signal processing, which is the time-frequency variant of the Wigner quasiprobability distribution
• Modified Wigner distribution function, used in signal processing
• Wigner semicircle distribution, a probability function used in mathematics
