|Charles Doolittle Walcott Medal|
|Awarded for||the encouragement and reward of individual achievement in advancing knowledge of Cambrian or Precambrian life and its history|
|Presented by||National Academy of Sciences|
Charles Doolittle Walcott Medal is an award presented by the National Academy of Sciences every five years to promote research and study in the fields of Precambrian and Cambrian life and history. 
The medal was established and endowed in 1934 by the Walcott Fund, a gift of Mary Vaux Walcott, in honor of paleontologist Charles Doolittle Walcott (1850-1927). The medal was sculpted by Laura Gardin Fraser.
Since 2008 the award has been linked to the Stanley Miller Medal and the two medals are now presented alternately, known collectively as the NAS Award in Early Earth and Life Sciences. Each medal is supplemented by a $10,000 award.
