Topology is a branch of mathematics concerned with spatial properties preserved under bicontinuous deformation (stretching without tearing or gluing); these are the topological invariants.

Topology may also refer to:

• Topology, the collection of open sets used to define a topological space
• Topology (journal), a mathematical journal, with an emphasis on subject areas related to topology and geometry
• Topology, is the study or science of places with applications in earth science, geography, human geography, and geomorphology
• Topology, a term used in architecture to describe spatial effects which cannot be described by topography, i.e., social, economical, spatial or phenomenological interactions
• Topology (electronics), a configuration of electronic components.
• Network topology, a term used to describe configurations of computer networks
