William Court Gully, 1st Viscount Selby PC, KC (29 August 1835 – 6 November 1909) was a British lawyer and Liberal politician.

[2] In 1880 and 1883 Gully unsuccessfully contested Whitehaven as a Liberal, but was elected for Carlisle in 1886, and continued to represent that constituency until his elevation to the peerage.

In April 1895 he was elected Speaker by a majority of eleven votes over Sir Matthew White Ridley, the Unionist nominee.

Rosebery did not want a Unionist as the new Speaker of the House of Commons, but rejected the two alternatives of Richard Haldane and Sir Frank Lockwood.

The Conservatives were not happy about his selection, and (recalling the scandal that engulfed his father) would greet his appearance in the House with cries of "Bravo, Gully!".
