Choa Chu Kang Bus Interchange is a bus interchange which mainly serves the residential neighbourhood of Choa Chu Kang in the North Region of Singapore.

It was later replaced by a bus interchange built beside the MRT station.

The old bus interchange was demolished to make way for the Jurong Region Line's Choa Chu Kang station.

Trans-Island Bus Services also had the operating base for Choa Chu Kang since 1990, where bus service SS7 was introduced from Choa Chu Kang to Woodlands, and on 10 March 1996, bus services 925 and 927 were extended to Choa Chu Kang.

[1] Since 1995, all bus services with the exception of Service 67 (Tampines), 179 (Bukit Panjang), 925 (Woodlands) and 927 (Bukit Panjang) were drawn under Choa Chu Kang Bus Package.
