Rozłazino [rɔzwaˈʑinɔ] is a village in the administrative district of Gmina Łęczyce, within Wejherowo County, Pomeranian Voivodeship, in northern Poland.

The first mention of the village dates back to 1356 and refers to the location of this village and the building of a church in a document issued by the commander of Danzig, Schwede von Pfelland.

In 1922 - 1923 two stained-glass windows with Kashubian, Polish and German names and the dates of the deaths of 58 parishioners who died in the First World War were installed in the presbytery of the church.

Soviet soldiers commit many rapes, and about a dozen Rozłazin residents are murdered.

On March 15, 1947, the name of the village was changed from Roslasin to Rozłazino.
