Near field may refer to:
*
Near-field (mathematics), an algebraic structure
*
Near-field region
The near field and far field are regions of the electromagnetic (EM) field around an object, such as a transmitting antenna, or the result of radiation scattering off an object. Non-radiative ''near-field'' behaviors dominate close to the ante ...
, part of an electromagnetic field
*
Near field (electromagnetism)
**
Magnetoquasistatic field, the magnetic component of the electromagnetic near field
**
Near-field communication (NFC) using the magnetic component of the electromagnetic near field (magnetoquasistatic field)

Near-field magnetic induction communication
A near-field magnetic induction (NFMI) communication system is a short range wireless physical layer that communicates by coupling a tight, low-power, non-propagating magnetic field between devices. The concept is for a transmitter coil in one de ...
, a technique for deliberately limited-range communication between devices
**
Near-field communication (NFC), a set of application protocols based on this

Near-field scanning optical microscope
Near-field scanning optical microscopy (NSOM) or scanning near-field optical microscopy (SNOM) is a microscopy technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves ...
