'''Selulosa''' merupakan [[senyawa organik]] dengan rumus ([[karbon|C]]<sub>6</sub>[[hidrogen|H]]<sub>10</sub>[[oksigen|O]]<sub>5</sub>)<sub>n</sub>, sebuah [[polisakarida]] yang terdiri dari rantai linier dari beberapa ratus hingga lebih dari sepuluh ribu [[ikatan glikosidik|ikatan β(1→4)]] unit [[glukosa|<small>D</small>-glukosa]].<ref name=Crawford>{{cite book

Selulosa merupakan komponen struktural utama [[dinding sel]]<ref>{{Cite web|title=Fungsi Dinding Sel Tumbuhan dan Bagian-bagiannya|url=https://www.sehatq.com/artikel/apa-saja-fungsi-dinding-sel-kenali-lebih-jauh-disini|website=SehatQ|language=id|access-date=2020-09-26}}</ref> dari [[tanaman hijau]], banyak bentuk [[ganggang]] dan [[Oomycetes]]. Beberapa spesies [[bakteri]] mengeluarkan selulosa untuk membentuk [[biofilm]].
Selulosa adalah senyawa organik yang paling umum di Bumi. Sekitar 33% dari semua materi tanaman adalah selulosa (isi selulosa dari [[kapas]] adalah 90% dan dari [[kayu]] adalah 40-50%). Selulosa tidak dapat dicerna oleh manusia, hanya dapat dicerna oleh hewan yang memiliki enzim [[selulase]].<ref>Cellulose. (2008). In ''[[Encyclopædia Britannica]]''.
