Sir Robert Harry Inglis, 2nd Baronet, FRS (12 January 1786 – 5 May 1855) was an English Conservative politician, noted for his staunch high church views.

He spoke strongly and successfully against the Catholic Relief Bill of 1847, claiming it would, if passed, weaken England’s Protestantism and allow Catholicism to grow (Cork Examiner, April 1847).

When Robert Grant, MP for Inverness Burghs, petitioned for Jewish relief in 1830, Inglis was violently opposed.

In 1851, when Lord Stanley (who became the Earl of Derby later that year) attempted to form a protectionist administration, Inglis was offered the presidency of the Board of Control, which he accepted initially, only to withdraw a few days later.

A major activity of Inglis's political career was the chairing of the select committee that controlled the House of Commons Library, of which he was a member for 14 years.

Due largely to his opposition to the Jewish reform measures, Disraeli apparently viewed Inglis with contempt, and described him as "a wretched speaker, an offensive voice, no power of expression, yet perpetually recalling and correcting his cumbersome phraseology.
