  We revisit agegraphic dark energy (ADE) model when the entropy associated
with the apparent horizon is in the form of Barrow entropy, $S\sim
A^{1+\delta/2}$, where $0\leq\delta\leq1$ indicates the amount of the
quantum-gravitational deformation effects of the horizon. The modification to
the entropy expression, not only change the energy density of ADE, but also
modifies the Friedmann equations due to thermodynamics-gravity conjecture.
Based on this, we investigate the cosmological consequences of ADE through
modified Barrow cosmology and disclose the effects of Barrow exponent $\delta$
on the evolutions of the cosmological parameters. We observe that, depending on
the values of $\delta$, the transition from early decelerated phase to the late
time accelerated phase occurs, and the equation of state (EoS) parameter $
w_{de} $ varies from quintessence $ -1<w_{de}<-1/3 $ to the phantom regime $
(w_{de}<-1)$. When $\delta=0$, all results of ADE in standard cosmology are
restored.
