Vasily Evgrafovich Yakovlev (Russian: Василий Евграфович Яковлев; also transliterated Vasiliy Ewgrafowitsch Jakovlev or Vasiliy Yevgrafovich Yakovlev; 9 February 1839 – 15 August 1908) was a Russian zoologist who studied fishes, molluscs and insects. He is not to be confused with Alexander Ivanovich Yakovlev, another entomologist. His name was spelled Wassily Ewgrafowitsch Jakowlew in French, in which he sometimes wrote.
