An optical fiber connection state determination system determines a state of connection between a first optical fiber configured to propagate a test light input from a light source and a second optical fiber in a connector configured to detachably connect an output side from which the test light is output in the first optical fiber and an input side of the second optical fiber to which the test light propagated by the first optical fiber and output from the first optical fiber is input, and includes: a measurement unit configured to measure an intensity of a reflected light reflected and propagating thorough the first optical fiber in the test light; and a determination unit configured to determine the state of connection between the first optical fiber and the second optical fiber in the connector based on the intensity measured by the measurement unit.
