Bertha Julia Aadnesen Reeder Richards (née Stone; October 28, 1892 – December 26, 1982) was the fifth general president of the Young Women's Mutual Improvement Association of the Church of Jesus Christ of Latter-day Saints (LDS Church) from 1948 to 1961.

In 1934, Bertha married William Henry Reeder, Jr., a municipal judge who was a widower with one son.

In April 1948, less than a year after returning to Ogden, Bertha Reeder succeeded Lucy Grant Cannon as the general president of the Young Women's Mutual Improvement Association.

In March 1961, William Reeder died, and in September that year Bertha was released and was succeeded as Young Women president by Florence S. Jacobsen.

During her tenure, the age groups in the Young Women organization were realigned to their current configuration and the "Gleaners" were renamed the "Laurels".
