'''Heptan''' (takođe poznat i pod nazivom '''dipropil metan''' ili '''heptil hidrid''') je [[ugljovodonik]] iz grupe [[alkan]]a sa [[molekulska formula|molekulskom formulom]] CH<sub>3</sub>(CH<sub>2</sub>)<sub>5</sub>CH<sub>3</sub>. Postoji devet [[izomer]]a heptana:
* n-Heptan
* 2-Metil heksan
* 3-Metil heksan
* 2,2-Dimetil pentan
* 2,3-Dimetil pentan
* 2,4-Dimetil pentan
* 3,3-Dimetil pentan
* 3-Etil pentan
* 2,2,3-Trimetil butan

Izomer n-heptan se može naći u [[nafta|nafti]]. On je veoma zapaljiv, i u dodiru sa vatom izaziva eksploziju.
