The Sultan Iskandar Building (BSI; Malay: Bangunan Sultan Iskandar) is a customs, immigration and quarantine (CIQ) complex in Johor Bahru, Johor, Malaysia. Located at the northern end of the Johor–Singapore Causeway, it is one of two land ports of entry to Malaysia on the Malaysia–Singapore border.

The building was named after the late Sultan Iskandar of Johor. Built as part of the Southern Integrated Gateway project on the former site of the Lumba Kuda flats, Kampung Bukit Chagar, the building occupies an area of 232,237 square metres (2,499,780 sq ft), making it the largest CIQ complex in Malaysia. The building started operations in 2008, replacing the former Johor Bahru Checkpoint.

From Malaysia, the main expressway leading to the building is the Johor Bahru Eastern Dispersal Link Expressway. After border inspection, vehicles (and pedestrians) continue onto the Causeway, eventually reaching the Woodlands Checkpoint in Singapore. Pedestrian access to the building is provided via the Johor Bahru Sentral railway station, which is linked to the building by a footbridge.
