We report new photometric lightcurve observations of the Lucy Mission target(11351) Leucus acquired during the 2017, 2018 and 2019 apparitions. We usethese data in combination with stellar occultations captured during five epochs(Buie et al. 2020) to determine the sidereal rotation period, the spin axisorientation, a convex shape model, the absolute scale of the object, itsgeometric albedo, and a model of the photometric properties of the target. Wefind that Leucus is a prograde rotator with a spin axis located within asky-projected radius of 3{\deg} (1$\sigma$) from J2000 Ecliptic coordinates($\lambda=208\deg$, $\beta=+77\deg$) or J2000 Equatorial Coordinates(RA=248$\deg$, Dec=+58$\deg$). The sidereal period is refined to$P_{sid}=445.683\pm0.007$ h. The convex shape model is irregular, with maximumdimensions of (60.8, 39.1, 27.8) km. The convex model accounts for globalfeatures of the occultation silhouettes, although minor deviations suggest thatlocal and global concavities are present. We determine a geometric albedo$p_V=0.043\pm0.002$. The derived phase curve supports a D-type classificationfor Leucus.
