Garreth is English, Irish in Origin.

Garreth is a modern spelling variant of the Welsh name Gareth, borne by a knight of the Round Table, brother of Gawain, in medieval Arthurian legend. The name’s precise etymology is uncertain; scholars often connect it with Welsh gwaredd, meaning “gentleness” or “compassion,” matching Sir Gareth’s courteous portrayal (nicknamed Beaumains, “fair hands”). Alfred, Lord Tennyson’s Idylls of the King renewed interest in the 19th century, and the name saw strong use in Wales and England through the mid-to-late 20th century.

Variant spellings include Gareth (the standard) and Garreth; Gaz is a familiar British nickname. Note that Garrett/Garret, frequent in the United States, look similar but descend from the Germanic Gerard (“spear-strong”) and are etymologically separate. Garreth remains comparatively rare, offering a subtle twist on a classic Welsh choice while keeping the enduring sense of “gentle, gracious.”
