We report the discovery of a possible classical nova located toward the Large Magellanic Cloud in data from the OGLE-IV Survey.

The nova is located at (RA, DEC) = (05:13:32.71, -68:38:00.4) J2000.0. It was discovered in the image acquired on 2018 Feb 27.07770 UT at an I-band magnitude of 11.5. The last pre-eruption image was taken four days earlier (on 2018 Feb 23.08035 UT), when the star had normal quiescent brightness of about 19.5 mag. There was not any minor planet at this place.

The progenitor was clearly visible in the OGLE images. It had the mean magnitude of I = 19.73 mag and color (V-I) = 0.57 mag. It showed eclipsing-like variability with a period of 2.84995 +/- 0.00003 d.

The star is located 15 arcsec from the reported position of Nova LMC 1996, within the uncertainty of the Nova LMC 1996 position. It is probably the second recorded eruption of this object.

Follow-up observations are encouraged.
