Isaac Jan Alexander Gogel (10 December 1765 – 13 June 1821) was a Dutch politician, who was the first minister of finance of the Batavian Republic and the Kingdom of Holland.

Gogel was born in Vught, the son of Johan Martin Gogel, a German officer in the service of the army of the Dutch Republic, and of Alexandrina Crul. He attended a French boarding school in Tilburg from 1776 to 1781. At the age of 16, he went to Amsterdam to apprentice for a career as a merchant, at the merchant house of Godart Kappel en Zoon. He started his own firm (Gogel, Pluvinot en Gildemeester) in 1791.

Gogel became politically active in 1792 when he joined the Patriot society Doctrina et Amicitia. He was a radical democrat and a unitarist. As part of the revolutionary committee in Amsterdam, he was involved with preparations for the Batavian revolution. Three times he went to the French army in the Southern Netherlands to negotiate for their support. He had to flee to Bremen at the end of October 1794, because the reigning regents in Amsterdam were arresting Patriots.

In January 1795, Gogel returned to Amsterdam after the risk of arrest had decreased. The French were entering the Netherlands to intervene, and Gogel played a major role in the peaceful takeover of the Amsterdam government for the Patriots. He became active in the local Amsterdam politics, advocating for unitarism, while his more radical democratic ideas faded away.

He was elected elector in the 1797 general election, but was not elected representative to the First National Assembly, Which he probably did not want due to his commercial activities. Gogel also declined other regional regional functions in these years. Nevertheless, he involved himself in the political developments and the creation of a constitution. Together with Willem Ockerse, he published the political journal 'De Democraten', where they shared their perspective on the developments.

After the 22 January 1798, coup d'état by general Herman Willem Daendels, he was appointed agent for finance and foreign affairs (pro tem) under the new Uitvoerend Bewind. However, the contraventions of the new, democratic, constitution of 1798 by the Pieter Vreede regime disaffected him, and he conspired with the other agents and again general Daendels to overthrow that regime in June 1798. He then became a member of the Uitvoerend Bewind himself for a short while, till elections had been held for a new Representative Assembly.

He was again appointed Agent, this time for Finance, by the new Uitvoerend Bewind. He now started on the reform of the Dutch system of public finance that was long overdue. He attempted to reorganize the tax system, but because this entailed abolition of the old, federal arrangements, he met strong resistance. He tried to attain three main objectives with his imposing General Tax Plan: construction of a system of regularly levied taxes, instead of the hodge-podge of ad hoc taxes and forced loans that the Republic had to rely on to make ends meet; a shift away from regressive, indirect taxes toward direct income taxes; and an equalization of the tax burden between different parts of the country. Besides, he proposed to form a new, national organisation to collect the taxes. His General-Taxation-Plan legislation was first proposed in 1799, but only enacted on 15 March 1801.

Modelled after the Louvre, Gogel envisioned a National art gallery for art-lovers and artists alike, that would promote the country's art heritage and educate its citizens. Starting in 1798, he started to create the Nationale Konst-Gallery (now Rijksmuseum). His motivation was partially developed out of the worries shared by many art lovers in the Netherlands at that time that the French saviors of freedom would take more than just one collection with them to Paris, as in 1795 the entire contents of Willem V's gallery had been installed in the Louvre. He decided on a place and two major types of art, and these were the Huis ten Bosch location with its magnificent Oranjezaal and the concepts "historieele" and "moderne" art.
