In mathematics, several different results due to Gottfried Leibniz are known as the Leibniz formula or Leibniz's formula:

• Leibniz formula for π
• Leibniz formula for the determinant of a matrix
• The product rule or some of its generalizations is also sometimes known as the Leibniz formula or Leibniz law
  • In particular, see Leibniz rule (generalized product rule).
• Leibnitz formula can also refer to the Leibniz integral rule
