An election to the Shetland Islands Council was held on 3 May 1990 as part of regional elections. Independents maintained control of the 25 seat council. The Shetland Movement gained two seats, bringing their total to seven. The Scottish National Party and Liberal Democrats also ran candidates for the first time.
Former Labour councillor Leonard Groat stood on an Independent Labour ticket in protest against his party's support for the closure of Montfield Hospital in Lerwick.[1]
