Boetius (Bote) Adamsz. à Bolswert (Bolsward, ca. 1580 – Antwerp, 25 March 1633) was a Dutch copper cutter and intermediate engraver.

This son of Adam Uytama and older brother of Schelte à Bolswert lived in Amsterdam from 1609, where he worked continuously for the leading painters of the time. In 1620 he became master in Antwerp.

He may have come into contact with Peter Paul Rubens around 1628, when he spent more time in Antwerp. Boëtius made several important engravings after designs by Rubens, including The Three Crosses and The Judgment of Solomon.

In Bolsward a street is named after him, the Bote à Bolswertstraat (Botestraat for short), which runs parallel to the Schelte à Bolswertstraat named after his brother. There is also a Bote van Bolwertstraat in Leeuwarden.
