She was a daughter of Ludwig II, Grand Duke of Hesse, and Princess Wilhelmine of Baden.
Marie was raised in austerity but was well educated by her mother, who took personal charge of her education but died when Marie was still very young.
She was only fourteen years old when the Tsarevich Alexander Nikolaevich, later Tsar Alexander II of Russia, fell in love with her while he was traveling to Western Europe.

She did not enjoy court life or the duties of representation as she was shy and of a withdrawn nature.
As a consequence she was not popular.

To avoid the harsh Russian winters, she spent long sojourns in the Crimea and in southern Europe.
During many summers she visited her family in Jugenheim, where she had spent her childhood.
Her marriage to Tsar Alexander II started as a love match and it was happy for some years, but Alexander II had many affairs and in 1866 he fell in love with Catherine Dolgorukova and had four children with his mistress.
Maria Alexandrovna was treated with respect by her philanderer husband
and she was much loved by her surviving children.
After a long illness, she died in 1880.
The Mariinsky Theatre in Saint Petersburg, the city of Mariinsk in Kemerovo Oblast, and the city of Mariehamn in Åland are named after her.
