Jane Spencer, Baroness Churchill VA (née Conyngham; 1 June 1826 – 24 December 1900) was an English aristocrat and companion of Queen Victoria.

Despite her long service, little is known of the details of Lady Churchill's personal life and time serving the queen, for she left no journals or memoirs.

The historian Helen Rappaport attributes this newly assigned role to the Queen "no doubt [being] impress[ed] with Churchill's discretion and dependability".

Rappaport writes of Churchill's personality, "[She] proved to be adept at self-effacement; she performed her duties with a combination of dignity, good humour, and vigilance".

[12] At Balmoral, Churchill frequently read to the queen from novels such as Jane Austen's Pride and Prejudice and George Eliot's The Mill on the Floss.

[12] In February 1872, Churchill was present on a drive from Regent's Park with the Queen when they were confronted by Arthur O'Connor, a teenage Irish nationalist.

[20] Queen Victoria's personal physician, Sir James Reid, at first withheld the news of Churchill's death as he feared it would upset the frail and labile monarch.

[21] The details of Churchill's personal life and time serving the Queen are little known, as she left no journals or memoirs; Victoria did not permit her ladies-in-waiting to keep a diary.
