Dragnet (show) features limited and generally problematic portrayals of LGBTQ+-adjacent characters and themes. When present, gender non-conformity or implied same-sex interactions are often linked to criminal activity or social deviance, serving as subjects for police investigation rather than being depicted with dignity or affirmation. The net impact is negative due to the judgmental and non-empathetic framing.

The 1967 Dragnet episode "The Big Search" depicts "female impersonators" as subjects in a criminal investigation. Their gender expression is presented as an unusual aspect of a subculture, primarily serving as plot points for police to navigate. The portrayal lacks affirming elements, instead associating gender non-conformity with a problematic social context without offering dignity or complexity.

The series consistently upholds a traditional moral code and respect for law and order, which often implicitly aligns with mainstream Christian values of the era. Characters expressing faith are generally portrayed with respect, contributing to a positive, if understated, depiction.
