Vel () (vel is "or" in Latin) or descending wedge is a symbol used to represent:

It was used by Russell and Whitehead in Principia Mathematica, where they called it the Logical Sum or Disjunctive Function. In Unicode the symbol is encoded {{unichar|2228|Logical or|html=}} and by \\vee and \\lor in TeX. The opposite symbol (∧) is called a wedge.
