An '''isoquant''' (derived from ''quantity'' and the Greek word ''{{transliteration|el|isos}}'', {{lang|el|ίσος}}, meaning "equal"), in [[microeconomics]], is a [[contour line]] drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs.<ref>{{cite book |last=Varian |first=Hal R. |title=Microeconomic Analysis |edition=Third |publisher=Norton |year=1992 |isbn=0-393-95735-7 |url=https://books.google.com/books?id=m20iQAAACAAJ }}</ref><ref>{{cite book |last=Chiang |first=Alpha C. |title=Fundamental Methods of Mathematical Economics |edition=Third |publisher=McGraw-Hill |year=1984 |isbn=0-07-010813-7 |pages=359&ndash;363 |url=https://books.google.com/books?id=6gcoAQAAMAAJ&pg=PA359 }}</ref> The x and y axis on an isoquant represent two relevant inputs, which are usually a factor of production such as labour, capital, land, or organisation. An isoquant may also be known as an "iso-product curve", or an "equal product curve".
