The Centre for Alternative Technology (CAT) is an eco centre in Wales dedicated to demonstrating and teaching sustainable development. It is open to visitors, holds residential courses; and publishes information on organic farming and gardening, and on ecologically-friendly living. CAT also runs several eco-businesses, including a consultancy service and mail-order catalogue.

The Centre was founded by businessman-turned-environmentalist Gerard Morgan-Grenville, and opened in 1974 in the disused Llwyngwern slate quarry in Machynlleth. It occupies a seven acre (2.8ha) site.

The Centre is open year-round, seven days a week.

The facilities and exhibits include:

• a water-powered funicular railway
• solar, hydro and wind power
• a low-energy house
• a site-wide electricity grid powered by renewable energy
• displays of organic gardening methods
• an hydraulic ram pump
• strawbale and rammed earth buildings
