- Removable singularity, a point at which a function is not defined but at which it can be so defined that it is continuous at the singularity
Natural sciences
- Gravitational singularity, a region in spacetime in which tidal gravitational forces become infinite
- Initial singularity, the gravitational singularity of infinite density before quantum fluctuations that caused the Big Bang and subsequent inflation that created the Universe
- Mechanical singularity, a position or configuration of a mechanism or a machine where the subsequent behavior cannot be predicted

Literary studies
- Temporal singularity, otherwise knows as a point of divergence, a concept in speculative fiction, usually an item or event triggered by an item that results in divergent narratives, in which the singularity alters the new timeline away from a prior "default" state, leaving behind a parallel universe in which the singularity did not occur; this is the basis of much of the "Alternate history" genre and may involve technology in "hard" science fiction, or may involve anything up to or including magic as the basis of the "what if?" scenario
