ALMA, the Atacama Large Millimetre/Sub-millimetre Array, is the largest current project in ground-based astronomy. It is an aperture synthesis array, optimized for high frequencies and currently under construction at a high, dry site in the Atacama desert of Northern Chile. When complete, it will provide unprecedented sensitivity, spatial resolution and imaging fidelity over the frequency range from 30 - 950 GHz. I will describe the key scientific goals of the project and outline its technical design. Interferometric observations with the first two ALMA antennas have recently been made, and construction is progressing rapidly. I will give an update on the current status and preparations for Early Science.
