  Trace formula may refer to:
  
  * Arthur–Selberg trace formula, also known as invariant trace formula, Jacquet's relative trace formula, simple trace formula, stable trace formula
  * Grothendieck trace formula, an analogue in algebraic geometry of the Lefschetz fixed-point theorem in algebraic topology, used to express the Hasse–Weil zeta function.
  * Gutzwiller trace formula: See Quantum chaos
  * Kuznetsov trace formula, an extension of the Petersson trace formula.
  * Local trace formula, an analog of Arthur–Selberg trace formula
  * Petersson trace formula
  * Selberg trace formula
  * Behrend's trace formula, or Behrend's fixed point formula a generalization of the Grothendieck–Lefschetz trace formula, that may be interpreted as a Selberg trace formula.
