Alexandrine of Mecklenburg-Schwerin (d. 1952)
Alexandrine of Mecklenburg-Schwerin (24 December 1879 – 28 December 1952) was Queen of Denmark from 1912 to 1947, as well Queen of Iceland from 1918 to 1944 as the spouse of King Christian X. She was the paternal grandmother of the current reigning Queen of Denmark, Margrethe II.

Alexandrine was a daughter of Frederick Francis III, Grand Duke of Mecklenburg-Schwerin and Grand Duchess Anastasia Mikhailovna of Russia. She was brought up with simplicity, and her early life was peripatetic, spending summers in Mecklenburg and the rest of the year in the south of France. She married Prince Christian of Denmark in 1898.

Alexandrine became crown princess in 1906 and queen consort of Denmark in 1912. She is not considered to have played any political role, but is described as being intelligent and a loyal support to her spouse. In spite of her German background, she was loyal to her new country and stood by her husband during the German occupation of Denmark during World War II.
