In logic, mathematics and linguistics, And (∧) is the truth-functional operator of logical conjunction; the and of a set of operands is true if and only if all of its operands are true. The logical connective that represents this operator is typically written as Template:Math or Template:Math.

"A and B" is true only if A is true and B is true.

An operand of a conjunction is a conjunct.

The term "logical conjunction" is also used for the greatest lower bound in lattice theory.
