'''Flexible Line Interpretation''' ('''FLI''') refers to a family of nonstandard graphics modes, and associated file formats, used on the Commodore 64 and other computers that use the VIC graphics chip. Hacks are used to transcend some of the limitations of the standard graphics modes, particularly the restrictions on how many different colors can be displayed in a character-sized cell.

An image to be displayed using FLI may use a standalone image file format, or it may be bundled with a viewer in an [[Commodore 64 binary executable|executable file]]. Some such executable files use an .SRF (Self-Running FLI) file extension.
