Ortnamnsregistret is an online gazetteer provided by Språkrådet (the Institute of Language and Peoples Heritage). It is a great reference to find Swedish place names, whether old or new, residential or landscape. At present it covers the entire country except for two counties – Örebro and Älvsborg. Searches can be made by county or for the entire country. It is a free website.
