Old Welsh () is the stage of the Welsh language from about 800 AD until the early 12th century when it developed into Middle Welsh. The preceding period, from the time Welsh became distinct from Common Brittonic around 550, has been called "Primitive" or "Archaic Welsh". Texts The oldest surviving text entirely in Old Welsh is understood to be that on a gravestone now in Tywyn – the Cadfan Stone – thought to date from the 7th century, although more recent scholarship dates it in the 9th century. A key body of Old Welsh text also survives in glosses and marginalia from around 900 in the Juvencus Manuscript and in . Some examples of medieval Welsh poems and prose additionally originate from this period, but are found in later manuscripts; Y Gododdin, for example, is preserved in Middle Welsh. A text in Latin and Old Welsh in the Lichfield Gospels called the "Surrexit Memorandum" is thought to have been written in the early 8th century but may be a copy of a text from the 6th or 7th centuries.

Elgu gave afterwards a horse, three cows, three cows newly calved, in order that there might not be hatred between them from the ruling afterwards till the Day of Judgement. Tudfwlch and his kin will not want it for ever and ever. Features The text shows many of the early spelling conventions of Welsh, when the basic Latin alphabet was used to represent the phonology of Old Welsh. At this stage, the use of to represent the lateral fricative ( > ) and to represent ( > ) had not been developed. The Latin letter was used to represent the diverse sounds and , which became and respectively, by the medieval period. Initial mutations, a major feature of all Insular Celtic languages, as well as internal consonant changes, do not appear to have been represented orthographically at this point. In some cases, the language used in the Memorandum has become obsolete, but other words are
