The characters of Oz, fictional characters on the television series about prison life, are a diverse mixture of inmates from various gangs and prison staff.

The corrections officers (COs) are mostly white (predominantly Irish and Italian) with many black and some Latino officers. The warden, Leo Glynn, is African American and started off his career as a CO at Oz. Most of the COs come from lower socio-economic classes. Some are amoral and prone to corruption. The main unit manager, Tim McManus, is the only authority figure who has not started off as a guard and this therefore gives him a different point of view about how to deal with the inmates. The rest of the non-correctional staff, such as Dr. Gloria Nathan and psychiatrist Sister Peter Marie ("Sister Pete") Reimondo, have a much more humane view of prisoners, and often push Glynn and the others to see the inmates as human beings. Overall, different factions within the staff are almost always at odds, trying to manage internal problems while keeping the public calm regarding the way the prison is being managed.

Due to Emerald City's unconventional configuration and routine, each new inmate is given a sponsor to help acclimate. Inmates are generally paired with sponsors of similar nationality, background, race, and/or religion, to help acclimate, with the help of someone with similar interests and beliefs. Specific requests for current Emerald City prisoners to be paired up with inbound inmates have occasionally been made and granted. Below is a list of inmates and sponsors.
