king of Kent in Anglo-Saxon England. He was the son of Erconberht and brother of Egbert, whom he succeeded in 673.

Hlothere appears to have shared power with his nephew Eadric (Egbert's son); laws still extant seem to have been issued in their joint names. A quarrel between them caused Eadric either to be banished or to flee the kingdom. He returned with an army of South Saxons, and in the ensuing battle Hlothere was defeated and mortally wounded.

The law code of Hlothere and Eadric is one of the oldest and most important sources of information on the structure of early English society. It is an enlargement of the earliest known Anglo-Saxon code, which was issued by Hlothere's ancestor Aethelberht I (reigned 560–616). Reflecting a primitive Germanic social organization, it seems to recognize a nobility of birth rather than of service, and a class of legal pleaders who were not king's ministers but “judges of the Kentish people.” Fines for crimes were listed prominently.
