Grand Duchess Elizabeth Mikhailovna of Russia (26 May 1826 – 28 January 1845) was the second child and daughter of Grand Duke Mikhail Pavlovich of Russia and Princess Charlotte of Württemberg who took the name Elena Pavlovna upon her conversion to the Orthodox faith.

Elizabeth was said to be the prettiest among her sisters and, like her mother, Elena Pavlovna, she was graceful in manners and well-educated.

By the end of 1843, Adolf, Duke of Nassau was visiting St. Petersburg and met Elizabeth for the first time.

After the wedding, the couple stayed in Russia for some time until they moved to Germany and took up residence in Castle Biebrich in Wiesbaden.

She and Adolf were happily married and the news that she was already pregnant with their first child brought great happiness to the couple.
