エベリーン・ド・ボリス＝レイモンド・マルコス（Eveline du Bois-Reymond Marcus、1901年10月6日 - 1990年1月31日）はドイツの生物学者。

彼女の動物学の教師であるエルンスト・マルコスと結婚後、研究は二人で進められたが、彼が常勤教授であったことと、彼女は報酬を受け取るような仕事を決して受け入れなかったので、文献の著者は Marcus, E とされていた。しかし、後には懐柔し 'Marcus, E. & E.' となり、'Marcus, E. du Bois-Reymond’の場合もあった。

エルンストがブラジル・サンパウロ大学人文科学部の哲学科の動物学の教員として招かれたため、彼らは1936年にベルリンを離れブラジルに移り住んだ

初期の頃（1924-1936）の研究はベルリンで行われ、後年（1936-1968）サンパウロに移る。彼らの出版物の全リストは、1924年から1970年にわたって約220ある。
