Dominic Charles Roberts Grieve is a British barrister and former politician who served as Shadow Home Secretary from 2008 to 2009 and Attorney General for England and Wales from 2010 to 2014. He served as the Member of Parliament (MP) for Beaconsfield from 1997 to 2019 and was the Chair of the Intelligence and Security Committee from 2015 to 2019.

In British politics, the Shadow Home Secretary is the person within the shadow cabinet who shadows the Home Secretary; this effectively means scrutinising government policy on home affairs including policing, national security, and matters of citizenship. The Shadow Home Secretary also formerly had responsibility for the criminal justice system and the prison service; these responsibilities are now held by the Shadow Justice Secretary. If the opposition party is elected to government, the Shadow Home Secretary often becomes the new Home Secretary, though this is not always the case. The office has been held by Labour MP Yvette Cooper since 29 November 2021.
