Eusebius Andrews, December 1606 to 22 August 1650, was a London lawyer and Royalist during the Wars of the Three Kingdoms, executed for his part in a 1650 plot to restore Charles II of England.

Andrews was removed for prosecuting a fellow member "contrary to the antiente custom of this house" and relocated to Cambridgeshire, near the Isle of Ely, where he continued to practice as a lawyer.

[5] He was in London during the period of political upheaval initiated when the Long Parliament assembled in November 1640; in May 1641, he brought charges of "treasonous words" against John Lilburne, a Puritan radical.

[12] Gell managed to avoid committing himself, although a former retainer named Benson was less careful; realising the conspiracy was going nowhere, Andrews prepared to leave for Holland but was arrested at Gravesend, Kent on 24 March 1650.

[13] On 30 March, Andrews was committed to the Tower of London charged with treason; when questioned, he pointed out the role played by Bernard as an Agent provocateur or instigator of the plot.

His arrest coincided with news of Charles II arriving in Scotland and on the recommendation of Sir Henry Mildmay, his trial was delayed until 16 August in hopes he would provide information on other suspects.

[15] Bradshaw had rejected the same arguments when used by Charles I at his trial and the verdict was never in doubt; Andrews was condemned to death on 19 August, although Parliament altered the usual penalty of hanged, drawn and quartered to beheading.

[16] Of the other conspirators, Benson was hanged in October, while Gell was found guilty of failing to communicate details of the plot; sentenced to life imprisonment, he was released on grounds of ill health in 1653.
