Sir Isaac Holden, 1st Baronet (7 May 1807 – 13 August 1897) was an inventor and manufacturer, who is known both for his work in developing the Square Motion wool-combing machine and as a Radical Liberal Member of Parliament.

Holden was born in the village of Hurlet near Glasgow. He was largely self-educated: his formal education was often disrupted. He was apprenticed for a short period as a draw boy for two hand weavers, but attended grammar schools run by the 'Old Radical' John Fraser. He became a pupil teacher and then sought to become a Wesleyan Minister, before teaching at schools in Slaithwaite and Leeds.

In 1829 Holden obtained a post at the Castle Academy in Reading, Berkshire. It was here that he developed a version of the Lucifer match, but his invention was superseded by John Walker of in 1827, who did not patent the invention. The following year Holden returned to Scotland to set up a night school in Glasgow, but after a brief period of teaching he moved in 1830 to become a bookkeeper at Townsends' worsted factory in Cullingworth near Bingley. Transferring to the technical side and becoming a manager, he spent his time at seeking to improve the process of combing wool.

Holden left Townsends in 1846 to set up a factory making Paisley Shawl middles at Pit Lane in Bradford. When the business failed two years later he formed a partnership with Samuel Lister. They worked together to develop the square motion wool-combing machine, which was patented by Lister in 1848, although Holden had drafted the patent. The origins of the machine became the subject of a lifelong dispute between the two men.

In 1848, trading as Lister & Holden, Isaac Holden set up a factory at St Denis near Paris, where over the next few years he perfected the square motion machine. He then set up factories in France, at Croix near Lille and at Reims, run by his nephews Isaac Holden Crothers and Jonathon Holden. In 1857 he bought out Lister and the firm was renamed Isaac Holden et Fils. In 1860 he and his sons, Angus and Edward, set up an experimental factory at Penny Oaks in Bradford and then in 1864 they opened the massive Alston Works at Bradford.
