In organic chemistry and biochemistry, an ether is functional group resulting from the condensation of alcohols.

Like esters, ethers are limited in their ability to form hydrogen bonds. They tend to be more hydrophobic than other, analogous condensation products (such as esters or amides). They are also much more resistant to hydrolysis than their ester or amide analogues.

In addition to the generic meaning, the term "ether" also commonly refers to the specific compound diethyl ether, CH3CH2OCH2CH3, also known as ethoxyethane. Diethyl ether was one of the first anesthetics used in surgery.

Despite their comparably attenuated reactivity, ethers can act as Lewis acids. For instance, diethyl ether forms a complex with boron compounds, such as boron trifluoride etherate, F3B:O(CH2CH3)2
