The SEG-Y (sometimes SEG Y) file format is one of several standards developed by the Society of Exploration Geophysicists (SEG) for storing geophysical data. It has become the most popular format in seismic exploration, allowing storage of traces, trace header data, and volume header data.

The format is an open standard, and is controlled by the SEG Technical Standards Committee, a non-profit organization.
