The Icelandic records in swimming are the fastest-ever performances by an Iceland swimmer.
The records are recognised and ratified by the Icelandic Swimming Association (Sundsamband Íslands - SSÍ).
[1] SSÍ maintains records in both long course (50m) and short course (25m) pools, in the following distances and strokes: Note: fjór is Icelandic for "four".
Also, the stroke order in the SSÍ report has breast before back.
All records were set in finals unless noted otherwise.
