The Clough Group is an Australian Engineering and Construction company based in Perth, Western Australia.

[4] Expansion was fuelled by civil engineering and infrastructure contracts from Western Australia's Pilbara iron ore boom.

[7] Acquisition of the Petrosea Group of Companies in 1984 (divested in 2009) was a basis for expansion in the South East Asian region.

[2][8][9] Around 1991, Clough Engineering took over Noyes Brothers, and traded as Noyes-Clough until 2002, when that branch of the company was purchased by Project Solutions Australia.

[16] In February 2019, Clough acquired Saulsbury's Gulf Coast downstream and chemical business unit in Houston, Texas.
