Fuser may refer to:
- The part of a laser printer that melts the toner onto the medium. It consists of a hot roller and a back-up roller. After toner is transferred onto the paper, the fuser applies heat and pressure to ensure that the toner stays on the paper permanently, which is why paper is warm when it comes out of a laser printer.
- A moniker used by Ernesto "Che" Guevara de la Serna, prior to his nickname Che. Short for "Furibundo Serna" (Furious Serna), due to his prowess on the rugby field.
- Fuser, a Unix command which lists processes currently using given files, filesystems, or sockets. For example:
# fuser -m -u /mnt/usb1 /mnt/usb1: 1347c(root) 1348c(guido) 1349c(guido)
