The couple announced their separation in November 2010 before simultaneously filing for divorce the following month.
Us Weekly confirms that the divorce proceedings have now been finalised, ending their three-year marriage.
According to court documents, neither side sought spousal support, and due to the lack of a prenuptial agreement any assets obtained since the couple's marriage will be split equally between both parties.
Earlier this year Johansson was reported to have begun dating fellow actor Sean Penn, although their relationship is believed to have ended after only three months.
Reynolds recently admitted that he is still going through a lot of pain in relation to his divorce, and said he still doesn't feel ready to begin dating again.
