Alalkomenes (Greek: Αλαλκομενές; before 1928: Μαμούρα Mamoura[2]) is a village and a community in the municipality of Livadeia, Boeotia, central Greece.

It is situated in a wide plain, 6 km northeast of Koroneia, 10 km east of Livadeia and 30 km west of Thebes.

[1] In 1928 the village Mamoura was renamed Alalkomenes after the nearby ancient town of Alalcomenae, that existed in the vicinity.

[2] The village became a separate community (together with Agios Athanasios) in 1928, when it was split from the community of Vrastamites.

[6] The village is served by Alalkomenes railway station, with local stopping services to Leianokladi and Athens.
