  Weakly compact can refer to:
  
  * Weakly compact cardinal, an infinite cardinal number on which every binary relation has an equally large homogeneous subset
  * Weakly compact set, a compact set in a space with the weak topology
  * Weakly compact set, a set that has some but not all of the properties of compact sets, for example:
