Halide minerals are those minerals with a dominant halide anion (, ,  and ). Complex halide minerals may also have polyatomic anions.

Examples include the following:
Atacamite 
Avogadrite  (K,Cs)BF
Bararite (β)
Bischofite 
Brüggenite 
Calomel 
Carnallite 
Carnallite 
Cerargyrite/Horn silver AgCl
Chlorargyrite AgCl, bromargyrite AgBr, and iodargyrite AgI
Cryolite 
Cryptohalite (a)
Dietzeite 
Eglestonite 
Embolite AgCl+AgBr
Eriochalcite 
Fluorite 
Halite NaCl
Lautarite 
Marshite CuI
Miersite AgI
Nantokite CuCl
Sal Ammoniac 
Sylvite KCl
Terlinguaite 
Tolbachite 
Villiaumite NaF
Yttrocerite (Ca,Y,Ce)F2
Yttrofluorite (Ca,Y)F2
Zavaritskite (BiO)F

Many of these minerals are water-soluble and are often found in arid areas in crusts and other deposits as are various borates, nitrates, iodates, bromates and the like.  Others, such as the fluorite group, are not water-soluble.  As a collective whole, simple halide minerals (containing fluorine through iodine, alkali metals, alkaline Earth metals, in addition to other metals/cations) occur abundantly at the surface of the Earth in a variety of geologic settings.  More complex minerals as shown below are also found.

Commercially significant halide minerals
Two commercially important halide minerals are halite and fluorite. The former is a major source of sodium chloride, in parallel with sodium chloride extracted from sea water or brine wells.  Fluorite is a major source of hydrogen fluoride, complementing the supply obtained as a byproduct of the production of fertilizer.  Carnallite and bischofite are important sources of magnesium.  Natural cryolite was historically required for the production of aluminium, however, currently most cryolite used is produced synthetically.

Many of the halide minerals occur in marine evaporite deposits. Other geologic occurrences include arid environments such as deserts. The Atacama Desert has large quantities of halide minerals as well as chlorates, iodates, oxyhalides, nitrates, borates and other water-soluble minerals. Not only do those minerals occur in subsurface geologic deposits, they also form crusts on the Earth's surface due to the low rainfall (the Atacama is the world's driest desert as well as one of the oldest at 25 million years of age).

Nickel–Strunz Classification -03- Halides 
IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses the Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).
