Built from Welsh Rhys, meaning ardor or enthusiasm, and popularized as a literary-style modern name.
Rhysand is a name of entirely literary origin, born from the imagination of author Sarah J. Maas in her 2015 fantasy novel A Court of Thorns and Roses and its sequels. Maas constructed the name on the foundation of the ancient Welsh name Rhys — pronounced 'Rees' — which derives from the Old Welsh 'Rhys' meaning 'enthusiasm,' 'ardor,' or 'fire,' and which has been borne by princes and warriors throughout Welsh history, including the twelfth-century ruler Rhys ap Gruffudd, known as the Lord Rhys.
By extending it with a fantastical suffix, Maas created something that feels grounded in Celtic linguistic heritage while being unmistakably otherworldly. The character Rhysand — the High Lord of the Night Court — became one of modern fantasy fiction's most discussed romantic figures, and the name accordingly leapt from the page into baby name registries worldwide. Few purely invented names travel so quickly from fiction to genuine usage, but Rhysand benefited from the particular intensity of the ACOTAR fandom and the broader 'romantasy' genre's extraordinary reach among millennial and Gen Z readers.
For parents choosing this name, it functions as both a literary tribute and a genuinely handsome name with audible Celtic roots. Its relationship to Rhys means it carries centuries of Welsh linguistic heritage beneath its fictional surface, giving the name a dual life: new enough to be singular, old enough to feel earned.
