In this article, we will take a look at the 25 most dangerous gangs in the US.

The term “gang” possesses two distinct connotations that enhance its practical significance. First and foremost, it implies a common attribute of gangs, which is their conspicuous street presence. Street-level socialization is a defining characteristic of gangs. Secondly, this term is closely tied to “street crimes,” denoting severe and violent offenses that frequently take place in public spaces. These transgressions often cause apprehension among residents, eroding informal social control mechanisms within a certain community.

Gangs are displaying growing sophistication, moving away from high-risk endeavors such as drug trade and arms trafficking. Today, these gangs are shifting their focus towards operations with reduced visibility and detection rates, such as human trafficking and white-collar crime. This shift is making the prosecution of gang-related crimes more challenging than ever. Gangs are also showing an alarming tendency to infiltrate law enforcement and military establishments to gather intelligence on rival groups and counter-crime initiatives. What’s even more concerning is the increasing access these gangs have to high-powered military-grade weaponry and equipment for their illicit pursuits.

It is an undeniable fact that the gang issue has evolved and entrenched itself over the past quarter-century. Media coverage tends to focus on regions where gang violence is on the rise, at times inadvertently fostering the perception of a widespread and ongoing escalation. However, a sudden spike in gang activity, particularly violent incidents in a specific area, does not necessarily signal an impending increase at the citywide, regional, statewide, or national level. Essentially, gang activity exhibits localized characteristics and follows cyclical patterns of fluctuations. Gang violence can be best understood as part of a recurring cycle, driven by the ever-shifting and volatile dynamics of conflict, rivalry, and competition among local gangs. For instance, after a period of relative calm, a triggering event, such as one gang encroaching on a rival gang’s turf, often leads to a violent incident, potentially prompting retaliation, and so forth. The localized nature of these cyclical patterns is the primary explanation for gang-related crime and violence across the United States. At any given moment, each city grappling with a gang issue, and each neighborhood within larger cities facing gang-related challenges is at its distinct point in the cycle of gang violence.

The United States harbors a diverse array of criminal groups and organizations, spanning from prison gangs and extortion operations to neo-Nazi entities. Although these groups may not always occupy the spotlight, they remain a persistent security concern for the country. Throughout the United States, the gang issue has undergone substantial changes over the years, marked by an increase in the number of gangs and gang members, the prevalence and use of firearms, and the establishment of a persistent, enduring gang presence in major U.S. cities, despite continuous turnover in membership. These trends provide reliable insights that can be used to characterize the overall gang issue. More recently, the involvement of one or a few gangs in criminal activities considered atypical for street gangs has garnered national attention. Recent instances encompass white-collar crimes, human trafficking, the operation of prostitution rings, penetration of governmental and criminal justice agencies, utilization of social networking sites and other online platforms for coordinating criminal actions, and association with domestic extremist groups.

While acknowledging the emergence and evolution of gangs’ criminal behaviors is essential, it is equally crucial to refrain from making sweeping generalizations about these trends, as though they are representative of most gangs across the United States. Without the support of credible and rigorous evidence collected over time, it would be imprudent to assume that the discovered involvement of a single gang or a few gangs in a particular criminal activity represents an emerging trend applicable to all gangs.

Our Methodology

While compiling our top roster of the list of gangs in the United States, we engaged in comprehensive research, sourcing information from a variety of reliable and diverse references. Our initial phase entailed the identification of over 30 gangs mentioned in these references. Whenever a gang was mentioned with precise metrics related to its size, impact in terms of notoriety, and illicit engagements, we organized this information and assigned relevant points.
