  We report the identification of a new, long period detached eclipsing binary
by the All-Sky Automated Survey for Supernovae (ASAS-SN). Combining V-band
photometry from ASAS-SN, ASAS and KELT, we constructed a light curve spanning
2006-2018. ASASSN-V J192543.72+402619.0 is an eccentric detached eclipsing
binary with an orbital period of $P\sim7.3$ yr, a minimum orbital eccentricity
of $e_{min}\sim0.2$ and a primary eclipse lasting $\sim160$ d. We also detect a
secondary eclipse that is $\sim 0.6$ mag shallower. Multi-band photometry
suggests that the more luminous component of the binary is an M-giant. Further
photometric and spectroscopic observations are encouraged.
