The Iver Huitfeldt class is a three-ship class of frigates that entered service with the Royal Danish Navy in 2012 and 2013.

The class is built on the experience gained from the Absalon-class support ships, and by reusing the basic hull design of the Absalon class the Royal Danish Navy have been able to construct the Iver Huitfeldt class considerably cheaper than comparable ships. The frigates are compatible with the Danish Navy's StanFlex modular mission payload system used in the Absalons, and are designed with slots for six modules. Each of the four stanflex positions on the missile deck is able to accommodate either the Mark 141 8-cell Harpoon launcher module, or the 12-cell Mark 56 ESSM VLS. The Peter Willemoes passed the British Flag Officer Sea Training test in 2015.

While the Absalon-class ships are primarily designed for command and support roles, with a large ro-ro deck, the three new Iver Huitfeldt-class frigates will be equipped for an air defence role with Standard Missiles, and the potential to use Tomahawk cruise missiles, a first for the Danish Navy.

The ships were constructed in blocks in Estonia and Lithuania. These blocks were then towed to Odense where they were assembled. Compared to the similar De Zeven Provinciën and Sachsen class frigates, the ships of the Iver Huitfeldt-class is lacking a gas-driven propulsion.

The builder's successor, OMT, suggests the type for the Procurement programme of the Royal Australian Navy's frigates, but built in Australia and modified for anti-submarine warfare. The type is also suggested for Canada's Single Class Surface Combatant Project.
