Beatrix is a Latin feminine given name, most likely derived from Viatrix, a feminine form of the Late Latin name Viator which meant "voyager, traveller" and later influenced in spelling by association with the Latin word beatus or "blessed". It is pronounced BEE-ə-triks in British English and the same or BEE-triks in North American English. Another North American English pronunciation however approximates that of most other languages: BAY-ə-triks, as shown by US dictionary entries for the former queen of the Netherlands.
Common forms of this name include Beatrice in English and Italian, Béatrice in French, Beatriz in Spanish and Portuguese, Beate in German, and Beata in Polish and Swedish. Common short forms are Bea and Trixie. See Beatrice for other derivatives.
