Spanish writer.

Daughter of Víctor Espina and Ascensión Tagle. In 1888, she published her first poem under the pseudonym Ana Coe Schnip. In 1893, she married Ramón de la Serna Cueto, with whom she moved to Chile. As mother of her children Ramón and Víctor, she returned to writing as a contributor to El Correo de Buenos Aires. After her return to Spain, she had three more children: José, Josefina, and Luis. In 1907, she won a literary contest with the short story El Rabión. After beginning her first novel, La niña de Luzmela, her marriage deteriorated, leading to a separation: her husband moved to Mexico, and she moved to Madrid, where she tried to publish her writings. During this period, she continued her contributions to newspapers such as ABC and other periodicals.

The publication of La niña de Luzmela in 1909 opened the doors to her success; it was followed by Despertar para morir (1910), Agua de nieve (1912), and La esfinge maragata (1914). She had her own weekly gathering, Los miércoles de Concha Espina, attended by Antonio Maura, Ortega y Gasset, Ricardo León, Antonio Machado, Gerardo Diego, Federico García Lorca, and Pilar Valderrama. In 1916, her novel La Rosa de los Vientos was published, along with the essay Mujeres del Quijote, illustrated by César Genaro Abín. In the following years, she published short stories. In 1920, she achieved great success with El metal de los muertos, inspired by the Riotinto miners' strike. This was followed by Dulce Nombre (1921), Simientes y Cuentos (1922), El Cáliz Rojo (1923), Tierras del Aquilón (1924), and Altar Mayor (1926). During these years, she received various accolades for her literary work: Alfonso XIII awarded her the Banda de Damas Nobles de la Reina María Luisa; she was proposed for a seat in the Real Academia de la Historia and was also proposed for the Nobel Prize nomination, though her candidacy was not successful by one vote.

In 1934, at the instigation of Clara Campoamor, she obtained a divorce. The war found her in Mazcuerras, where she stayed and was reunited with her children after the entry of Francoist troops in Santander. She supported the rebels and became a member of the Falange. She documented her experiences during the war in a series of stories in which other female family members participated: Luna roja, Retaguardia y Esclavitud y libertad. Diario de una prisionera. The loss of her vision affected her literary output in the following years, although she continued writing, both novels and essays, as well as journalistic contributions. Her last novel dates from 1953, Una novela de amor. Among the last recognitions she received was another nomination for the Nobel Prize, the Gran Cruz de Alfonso X, the Medalla de la Academia de Letras y Artes of the city of Córdoba, and the Medalla de Oro del Mérito al Trabajo.
