Opservatorij Arecibo nalazi se pokraj mjesta Arecibo na Portoriku. Izgrađen je u periodu između 1960. i 1963.
Opservatorij djeluje kao američki Nacionalni centar za astronomiju i ionosferu i njim upravlja američki Univerzitet Cornell.
U Arecibu se nalazi najveći radioteleskop na svijetu. Prečnik njegovog tanjira je 305 metara. Radioteleskop u Arecibu jedinstveno je projektovan da bi tražio signale vanzemaljskog života, usredotočujući se prema hiljadama sunčevih sistema u dometu od 1.000 do 3.000 MHz. Takvi signali još nisu nađeni.
