718 Erida is a minor planet orbiting the Sun. It was discovered at Vienna on September 29, 1911, by Austrian astronomer Johann Palisa, and was named for Erida Leuschner, daughter of astronomer Armin Otto Leuschner. It is orbiting at a distance of {{val|3.06|ul=AU}} with a period of {{convert|1951.2|days|years|2|disp=out|abbr=on}} and an eccentricity of 0.20. The orbital plane of this asteroid is inclined by an angle of 6.9° to the plane of the ecliptic.

Photometric observations made during 2009 were used to produce a light curve for this asteroid that showed a rotation period of {{val|17.447|0.002|u=hours}} with a brightness variation of 0.37 in magnitude. It spans a girth of approximately 72 km.
