'''Logical conjunction''' is an [[logical operation|operation]] on two [[logical value]]s, typically the values of two [[proposition]]s, that produces a value of ''true'' if and only if both of its operands are true.
The [[truth table]] of '''p AND q''' (also written as '''p ∧ q''', '''p & q''', or '''p<math>\cdot</math>q''') is as follows:
{| align="center" border="1" cellpadding="8" cellspacing="0" style="background:lightcyan; font-weight:bold; text-align:center; width:45%"
|+ '''Logical Conjunction'''
|- style="background:paleturquoise"
! style="width:15%" | p
! style="width:15%" | q
! style="width:15%" | p ∧ q
|-
| F || F || F
|-
| F || T || F
|-
| T || F || F
