The Patrulleros de Zona Marítima (PZM) (English: Maritime Zone Patrol Boats) are a series of offshore patrol vessels being built for the Navies of Chile and Colombia.

Argentina also expressed an interest in building these ships.

The design of the PZM was developed by Fassmer GmbH & Co. KG, a German company to meet the Chilean Navy's requirements under the Danubio IV project. The contract for ASMAR to build the PZMs was signed on May 20, 2005, with Northrop Grumman, Sisdef (a consortium of BAE Systems and shipbuilder ASMAR) and Rohde & Schwarz participating as main subcontractors at a cost of US$54 million to be commissioned by 2012. The vessels will be operated by the Coast Guard Service of the Chilean Navy and they will conduct patrol missions in Chile's exclusive economic zone (EEZ). The design of the Proyecto Patrulleros de Zona Marítima is being promoted by Chile as a common platform for South American navies through the Proyecto Patrullero de Alta Mar Regional (or Regional Offshore Patrol Ship) committee.

On 2008, Argentina ordered up to five PZM at a cost of US$120 million as part of its own Patrulleros de Alta Mar (PAM) programme to be constructed at its Río Santiago Shipyard. In 2010 the Argentine Government launched the construction of the first four at the Tandanor Shipyard.

Colombia ordered three vessels to be built at its COTECMAR shipyard in Cartagena, out of six planned until 2020.
