She was born at the Royal Palace of Milan to Rainer Joseph of Austria and his wife Elisabeth of Savoy. Named Adelaide, or known as Adele in the family, she held the title of Archduchess of Austria. Her father was the Viceroy of Lombardy-Venetia and was a son of the Holy Roman Emperor Leopold II and Maria Luisa of Spain. Her mother was a member of the House of Savoy and a daughter of the then Prince of Carignano, the head of the junior branch of the House of Savoy who ruled the Kingdom of Sardinia.
Duchess of Savoy
On 12 April 1842, at the Palazzina di caccia di Stupinigi, she married Victor Emmanuel of Savoy. The marriage was used to strengthen relations between the House of Savoy and that of the House of Habsburg but was viewed by many people of the time to increase Austrian power in Italy.
Victor Emmanuel was her first cousin and heir apparent to the King of Sardinia. He was styled the "Duke of Savoy" prior to succession. Adelaide thus took on the style of "Duchess of Savoy". She maintained her style of Imperial & Royal Highness till she became Queen.
Her husband's mother Maria Theresa of Austria retained great influence over her son throughout his life. Her mother-in-law was also her first cousin, both she and Adelaide being grandchildren of Emperor Leopold II. Adelaide and her husband of thirteen years had eight children. Four of these went on to have further progeny. Her husband had various extramarital affairs throughout the marriage. Adelaide was a quiet and religious woman and had had a strict upbringing. A loving wife and frequently would give to charity.

In March 1849 her father-in-law King Charles Albert abdicated after the events of the Revolutions of 1848. Her husband succeeded as Victor Emmanuel II of Sardinia. During her tenure as queen consort she had three further children all of which died in infancy. On 8 January 1855 she gave birth to a son who was styled the "Count of Genevois". Days later Queen Maria Theresa died on 12 January 1855. Adelaide went to the late queens funeral on 16 January and returning to the palace caught a cold. She died four days later at the Royal Palace of Turin having had an acute attack of Gastroenteritis. Another story says that Adelaide died of her burns after stepping on a match that set fire to her clothes. She was buried at the Royal Basilica of Superga.
