Wojciech Bogumił Jastrzębowski (Polish pronunciation: ['vɔjt͡ɕɛx jastʂɛm'bɔfski]; 19 April 1799 – 30 December 1882) was a Polish scientist, naturalist, and inventor; professor of botany, physics, zoology, and horticulture at Instytut Rolniczo-Leśny in Warsaw's Marymont district; a founder of ergonomics; and an insurgent in Poland's November 1830 Uprising.

He was a member of a Polish noble (szlachta) family – originally from the village of Janowiec-Jastrząbki in Janowiec Kościelny, in Pobożany parish – bearing the Pobóg coat of arms.

He created the Zakład Praktyki Leśnej, the first institution for the improvement of professional forestry and gamekeeping, in Feliksów near Brok.

During the 1831 Battle of Olszynka Grochowska in defense of Warsaw, during Poland's November 1830 Uprising, Jastrzębowski framed the first proposal of a constitution for a Europe united as a single republic with no internal borders, with a unified legal system, and with institutions staffed by representatives of all of Europe's peoples.

Poland's Mazowsze Province features a cycling path, named after Jastrzębowski, from Ostrów Mazowiecka to Brok.
