The Las Vegas Crime Lab is a scientific laboratory located in Las Vegas, which uses primarily forensic science for the purpose of examining evidence from criminal cases while determining who is responsible for the crime that has been committed.

Employees of the Crime Lab are known as criminalists; this includes both CSIs doing mostly field work and lab techs doing mostly lab work.

CSIs are equipped with guns in the field, but are not considered police officers. CSIs often mention this to suspects to make them feel more comfortable. ^{[citation needed]}

The Crime Lab is headed by Undersheriff Conrad Ecklie and reports directly into the Sheriff's office. ^{[citation needed]} Ecklie was once the Assistant Director and also former Dayshift supervisor of the Crime Lab, but was promoted to Undersherrif after former Undersheriff Jeffrey McKeen was arrested for killing CSI Warrick Brown in the Season 8 opening episode, "For Warrick".

In addition to that, all CSI personnel including some of the techs usually wear stab vests if they're out in the field, doing work or investigating any crime scenes. As well as giving the tags which ID'ds them as LVPD CSIs, they also give the wearer's surname and have various pockets useful for carrying small objects.^{[citation needed]}
