Eduarda (minor planet designation: 340 Eduarda) is a main belt asteroid that was discovered by German astronomer Max Wolf on 25 September 1892 in Heidelberg.^[2] It was named after German banker and amateur astronomer Heinrich Eduard von Lade.

Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana, during 2006 gave a light curve with a period of 8.04 ± 0.02 hours and a brightness variation of 0.25 ± 0.03 in magnitude.^[3]
