A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations.
The creation of a national DNA database within the U.S. was first mentioned by the Technical Working Group on DNA Analysis Methods (TWGDAM) in 1989.

Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

A cold hit is of value in referring the police agency to a specific suspect but is of less evidential value than a DNA match made from outside the DNA Databank. [49]
