Upper Lamptrai, or Lamptrai Kathyperthen (Ancient Greek: Λαμπτραὶ καθύπερθεν) or Lamptra Kathyperthen (Λάμπτρα καθύπερθεν), was a deme of ancient Attica. Lamptrai Kathyperthen and nearby Coastal Lamptrai (Lamptrai Paraloi) were between Anagyrus, Thorae, and Aegilia.[1] At Lamptra the grave of Cranaus was shown.[2][3]
The site of Upper Lamptrai was near modern Lambrika.[4][5]
