Everstiluutnantti (Lieutenant colonel, Swedish: Överstelöjtnant[1]) is an officer's rank in Finland, immediately above Majuri (Major) and below Eversti (Colonel).

During peacetime, an everstiluutnantti is the commander of a battalion or a chief of staff for a regiment or brigade.

The rank requires completion of a staff officer course.

[2] Only a few reservists have obtained the rank of everstiluutnantti.

It requires active participation in national defence and a demanding wartime position.
