Colby railway station (Manx: Stashoon Raad Yiarn Cholby) is a small railway station on the southern edge of the village of Colby in the south of the Isle of Man served by the Isle of Man Railway; it forms part of the sole remaining section of the network which once covered over 46 miles island-wide.

The building here survived through nationalisation and was demolished in 1980, leaving no shelter for waiting passengers.

Until 1991 the pointwork was still in place at the northerly end of the railway station but this was removed when remedial works were carried out at this time.

In 1991 the shelter from Braddan Bridge on the long-abandoned line to Peel was refurbished and moved here, but since the railway station received platforms on both up and down sides of the loop in conjunction with an all-island sewerage network in 2002, the waiting shelter is no longer at platform height, being left in-situ at a lower point giving it an unusual appearance in respect of the actual platforms.

The railway station is unique in being the only one on the line to not carry bi-lingual railway station nameboards because the name translated carries exactly the same spelling, but this does lead to an inconsistency of naming along the line.
