In mathematics, it generally refers to any element of an abstractly-defined vector space over a field.
- Vector (spatial): In physics and engineering, vector most often refers specifically to an object that has a special relationship to the spatial coordinates/directions, i.e. an element of a tangent bundle.
  - Related concepts include: four-vector (the generalization to space and time in relativity), pseudovector, vector calculus, vector bundle, unit vector, null vector and normal vector.
- If the vector space is finite-dimensional, its vectors are commonly denoted by matrices with dimensions n×1 (column vector) or 1×n (row vector).
- Other specific types of vector include: probability vector.
In computer science:
- In computer programming, the same as list or one-dimensional array.
  - a vector supercomputer has SIMD operations that work on arrays of several numbers at once
  - dope vector
  - In operating systems, a memory location
  - In Java, java.util.Vector is a standard class implementing a dynamically sized array.
