Mary S. B. Shindler (also, Mary S. B. Dana and Mary Dana Shindler; 15 February 1810 – 1883) was an American poet, writer, and editor of the southern United States. She was a frequent contributor to popular periodicals, and a successful hymnwriter of the mid-19th century.

Shindler came to Texas in 1865. Her earliest book was a volume of poems called The Southern Harp. This was followed by The Northern Harp, The Parted, Young Sailor, and Forecastle Tom. She also published a book on spiritual phenomena. During a temporary residence in Memphis, she edited The Voice of Truth, a journal devoted to the interests of spiritualism and reform. Selecting some of the most popular airs, she added poems to them, a result of her own sorrow and domestic bereavement; music thus immortalized her verse. Her best known poem was "Pass Under the Rod", written when sorrow and faith were strong.
