alt=|thumb|OTMA from left to right, Maria, Tatiana, Anastasia and Olga Nikolaevna in 1914. OTMA was an acronym sometimes used by the four daughters of Emperor Nicholas II of Russia and his consort, Alexandra Feodorovna, as a group nickname for themselves, built from the first letter of each girl's name in the order of their births: Ольга – Olga Nikolaevna Romanova (15 November 1895 – 17 July 1918) was the eldest daughter. Татьяна – Tatiana Nikolaevna Romanova (10 June 1897 – 17 July 1918) was the second daughter. Мария – Maria Nikolaevna Romanova (26 June 1899 – 17 July 1918) was the third daughter. Анастасия – Anastasia Nikolaevna Romanova (18 June 1901 – 17 July 1918) was the youngest daughter.

Note that the Roman and Cyrillic forms of all four of the initial letters are identical in printed form.
