甚高频全向信标（VHF Omni-directional Range，通常缩写为VOR）是一种飞机上使用的短距离无线电导航系统，利用接收地面上的固定无线电信标网络所发射、介于108至117.95兆赫的超高频信号来判断飞机本身的位置，以维持在设置的航道上。最早是在1937年由美国开始发展并在1946年开始部署，VOR已是今日全球航空产业的导航系统标准，应用遍及民用航空与通用航空领域。但近年来由于GPS的逐渐普及，反而有部分机场撤除原本所设VOR的现象。

在许多机场，VOR通常会与测距仪（DME）甚至军用的战术空中导航系统（TACAN）并设在同一个位置。当与TACAN并设时，两系统会合称为「VORTAC」。

VHF Omni Directional Radio Range (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR is the standard air navigational system in the world, used by both commercial and general aviation. By 2000 there were about 3,000 VOR stations around the world including 1,033 in the US, reduced to 967 by 2013 with more stations being decommissioned with the widespread adoption of GPS.
