Perovskite nanomaterials have been revealed as highly luminescent structures regarding their dimensional confinement. In particular, their promising potential lies behind remarkable luminescent properties, including color tunability, high photoluminescence quantum yield, and the narrow emission band of halide perovskite (HP) nanostructures for optoelectronic and photonic applications such as lightning and displaying operations. However, HP nanomaterials possess such drawbacks, including oxygen, moisture, temperature, or UV lights, which limit their practical applications. Recently, HP‐containing polymer composite fibers have gained much attention owing to the spatial distribution and alignment of HPs with high mechanical strength and ambient stability in addition to their remarkable optical properties comparable to that of nanocrystals. In this review, the fabrication methods for preparing nano–microdimensional HP composite fiber structures are described. Various advantages of the luminescent composite nanofibers are also described, followed by their applications for photonic and optoelectronic devices including sensors, polarizers, waveguides, lasers, light‐down converters, light‐emitting diode operations, etc. Finally, future directions and remaining challenges of HP‐based nanofibers are presented. Fiber‐shaped halide perovskite composites offer excellent luminescent properties with color tunability and emission efficiency for optoelectronic and photonic applications. In addition, composite fibers possess high ambient and mechanical stability, promoting their applications in stretchable/flexible devices. This review highlights the fabrication, morphology, properties, and applications of halide perovskite/polymer composite fibers.
