Elena Sergeevna Bulgakova (in Russian: Елена Сергеевна Булгакова; 21 October 1893 - 18 July 1970) was a Soviet author and intellectual.

In collaboration with her husband, Mikhail Bulgakov, she participated in the writing of The Master and Margarita, a central work of Russian literature.

[1] Her family was connected to the Moscow theater world; for example, her sister Olga worked as a secretary for Vladimir Nemirovich-Danchenko.

[9] While the bulk of the work was undertaken by her husband, it was a shared creative process, as she was his muse, and he resumed writing after marrying her.

[12] Bulgakova remained connected to the Soviet intellectual, and even dissident, circles, receiving visits from figures such as Anna Akhmatova between 1942 and 1944.
