1900 Icelandic parliamentary election

Parliamentary elections were held in Iceland in September 1900.

Electoral system
The 30 elected members of the Althing were elected from single or double member constituencies by a three-round system; in the first two rounds, a candidate receiving a majority of the vote was elected; if seats were still unfilled after the second round, a third round was held using first-past-the-post voting. Voting took place at a single polling place in each constituency and was done publicly. A further six members were appointed to the upper house by the Danish monarch.

Suffrage was limited to men aged 25 or over who were not in receipt of poor relief and who met one of several set requirements including being a civil servant, being a graduate of a university or seminary, or meeting various tax criteria (for farmers, paying more than the minimum tax; for burghers or fishermen, paying eight króna of local taxes; for property owners, paying twelve króna of local property taxes). This limited the number of voters to 7,329 from a population of 78,203.

Results
3,573 of the 7,329 registered voters participated in the elections.
