Lucy H. Washington (née, Walker; January 4, 1835 – September 2, 1913) was an American poet and social reformer of the long nineteenth century, active in the temperance movement.

For many years, she was engaged in Woman's Christian Temperance Union (WCTU) work, having given addresses in 24 states, and extended her efforts across the country.

From her Clover Street Seminary days, her verses frequently appeared in print, with occasional prose sketches.

After graduation, she devoted three years to teaching and was at the time of her marriage preceptress of the Collegiate Institute in Brockport, New York.

In Jacksonville, Illinois, in 1874, Washington became a leader in the temperance crusade movement, and in response to the needs of the time, became an effective public speaker.

She became better-known to the public through commendatory press reports, which led to repeated and urgent calls for lectures.
