Nonlocality may refer to:

  • Action at a distance, the concept in physics of nonlocal interactions
  • Quantum nonlocality, nonlocal phenomena in quantum mechanics
  • Nonlocal Lagrangian, a type of Lagrangian (a mathematical function)
  • Nonlocal operator, which maps functions on a topological space to functions, in such a way that the value of the output function at a given point cannot be determined solely from the values of the input function in any neighbourhood of any point.
