Rajko is a South Slavic masculine name built with the diminutive suffix -ko. In Serbian, Croatian, Slovene, Macedonian, and Bulgarian, it is read Rai-ko and is commonly explained as deriving from Slavic raj “paradise, heaven,” yielding senses like “heavenly” or “from paradise.” Some scholars also connect it with the prolific Slavic root rad- (“willing, glad, eager”), making Rajko a pet-form parallel to Radko/Rado- names meaning “one who is joyful or willing.”

Attested in church and civil records across the Balkans since the 18th–19th centuries, the name saw steady 20th‑century use, helped by figures such as Serbian footballer Rajko Mitić and Croatian director Rajko Grlić. Variants and cognates include Bulgarian Rayko/Raiko (Райко), Macedonian/Serbian Рајко, Slovene/Croatian Rajko, Hungarian Rajkó; feminine Rajka appears regionally. Nicknames include Raja, Rajo, and, in Bulgarian, Raicho. Related surnames (e.g., Rajkov, Rajković) reflect long-standing patronymic use.
