  Isotopy may refer to:
  
  ## Mathematics
  
  * Homotopy#Isotopy, a continuous path of homeomorphisms connecting two given homeomorphisms is an isotopy of the two given homeomorphisms in homotopy
  * Regular isotopy of a link diagram, an equivalence relation in knot theory
  * Ambient isotopy (or h-isotopy), two subsets of a fixed topological space are ambient isotopic if there is a homeomorphism, isotopic to the identity map of the ambient space, which carries one subset to the other
  * Isotopy of quasigroups. See Quasigroup#Homotopy and isotopy.
  * Isotopy of loops, a triple of maps with certain properties.
  * Isotopy of an algebra, a triple of maps with certain properties.
  
  ## Semiotics
  
  * Isotopy, a repetition of a basic meaning-trait (seme); the direction taken by an interpretation of the text
