Sarah D. Winans (née Darst; 1841–1915) was an American charitable organization leader who served as the 21st National President of the Woman's Relief Corps (WRC).

[2] From the beginning of the Civil War until its close, she was assiduous in promoting the work of the U.S. Sanitary Commission, and in looking after the comfort of the soldier in the hospital, on the field, and in the camp.

[2] In San Francisco in 1903, at the 22nd annual convention of the WRC,[5] she was elected National President without a dissenting vote.

Hundreds of bearing pecan trees and 400 rose bushes which she helped train with her own hands contribute to the memory of the 13,920 soldiers lying in the cemetery.

[2] On May 30, 1911, she presented a monument and tablet (upon which were memorialized the history of the gift of the park to the WRC, and their transfer of it to the United States Government) to Belle C. Harris, national president of the WRC, who in turn presented it to a representative of the Government, Captain Bryant.

[3] Her most forcible speech was delivered at the executive session of the National Council of Women of the United States at Indianapolis, February 2, 1904; her subject was "Peace and Arbitration," giving its fundamental principle as love, serving charity without ostentation.

[2] Winans was a regent of the Memorial University at Mason City, Iowa, established by the Grand Army of the Republic (GAR) and the WRC.
