In organic chemistry, isopropyl is a substituent form of propane, the three-carbon alkyl functional group. As an isomer of propyl, bonding to an R group occurs at the secondary (2°) carbon.

Isopropyl (common name) is also known as 1-methylethyl (IUPAC); shorthand notations for this alkyl are i-Pr,ⁱPr, or Prⁱ (some care has to be taken when using the abbreviation 'Pr', as it is the same as for the chemical element Praseodymium).
