  We have investigated tidal forces and geodesic deviation motion in the
4D-Einstein-Gauss-Bonnet spacetime. Our results show that tidal force and
geodesic deviation motion depend sharply on the sign of Gauss-Bonnet coupling
constant. Comparing with Schwarzschild spacetime, the strength of tidal force
becomes stronger for the negative Gauss-Bonnet coupling constant, but is weaker
for the positive one. Moreover, tidal force behaves like those in the
Schwarzschild spacetime as the coupling constant is negative, and like those in
Reissner-Nordstr\"{o}m black hole as the constant is positive. We also present
the change of geodesic deviation vector with Gauss-Bonnet coupling constant
under two kinds of initial conditions.
