The Malaysia–Singapore Second Link (Malay: Laluan Kedua Malaysia–Singapura, Chinese: 马新第二通道) is a bridge connecting Singapore and Johor, Malaysia.

The bridge supports a dual-three lane carriageway linking Kampong Ladang at Tanjung Kupang, Johor to Jalan Ahmad Ibrahim at Tuas, Singapore.

The bridge is directly accessed via the Ayer Rajah Expressway, along with other supporting roads around the vicinity of the Tuas industrial area.

The idea of building a second link between Malaysia and Singapore was first raised in July 1980 by then-Menteri Besar of Johor, Othman Saat.

On 22 March 1994, an inter-government agreement was signed defining the responsibilities of both governments with regard to the design, construction, operation, and maintenance of the bridge.

Each government was responsible for the construction of the portion the bridge which fell within its borders, based on a common agreed design.

The major components of the project are the Second Crossing bridge, forty-four kilometres of expressways, a Customs, Immigration and Quarantine complex, three toll plazas, two rest and service areas and other ancillary facilities.

It was officially opened on 18 April the same year by the Prime Ministers of both countries, namely Dato' Seri Dr. Mahathir Mohamad of Malaysia and Goh Chok Tong of Singapore.
