Seleucus is Greek in Origin.

From Ancient Greek Σελεύκος (Seleukos), Latinized as Seleucus, this name is etymologically linked to Greek leukos “white, bright,” perhaps reinforced by selas “radiance.” Scholars consider the formation uncertain, but the longstanding association with the Indo-European root *leuk- (“light, brightness”) supports the sense “the bright one” or “shining.” In Modern Greek the spelling is unchanged (Σελεύκος), though often transcribed phonetically as Selevkos.

Seleucus flourished in the Hellenistic world, most famously borne by Seleucus I Nicator (founder of the Seleucid Empire), with several successor kings repeating the name. It also appears in learned contexts through Seleucus of Seleucia, a 2nd‑century BCE astronomer. Later Byzantine and modern use is rare, lending the name an antique, scholarly aura today. Variants and forms include Seleukos (scholarly transliteration), Séleucos (French), Seleuco (Spanish/Italian/Portuguese), and related toponyms/feminine counterpart Seleukeia/Seleucia. Cognate concepts appear in Leucius/Leukios (“white”).
