340 Eduarda is a main belt asteroid that was discovered by German astronomer Max Wolf on 25 September 1892 in Heidelberg. 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.
