  We report the value of the electric quadrupole moment of $^{209}$Bi extracted
from the atomic data. For this, we performed electronic structure calculations
for the ground $^4S^o_{3/2}$ and excited $^2P^o_{3/2}$ states of atomic Bi
using the Dirac-Coulomb-Breit Hamiltonian and the Fock space coupled cluster
method with single, double, and full triple amplitudes for the three-particle
Fock space sector. The value of the quadrupole moment of $^{209}$Bi,
$Q(^{209}$Bi$)=-418(6)$~mb, derived from the resulting electric field gradient
values and available atomic hyperfine splittings is in excellent agreement with
molecular data. Due to the availability of the hyperfine constants for unstable
isotopes of Bi, current atomic calculation allows also to correct their
quadrupole moments.
