Selection of participants
Contestants from ninety-two countries and territories were selected to compete in the pageant. Fourteen of these delegates were appointees to their titles after being a runner-up of their national pageant or an audition process or other internal selection, while three were selected to replace the original dethroned winner.

Liesbeth Claus, the third runner-up of Miss Belgium 2017, was appointed to represent Belgium after Romanie Schotte, Miss Belgium 2017, chose to compete at Miss World 2017 due to conflicting schedules of the two pageants. Kseniya Alexandrova, the first runner-up of Miss Russia 2017, was also appointed to represent Russia after Polina Popova, Miss Russia 2017, chose to compete at Miss World 2017. Katarzyna Włodarek, the second runner-up of Miss Polonia 2016, was appointed to represent Poland after the Miss Polonia pageant was postponed to late November following the Miss Universe pageant.

Mira Simeonova, Miss Universe Bulgaria 2017, originally was supposed to represent Bulgaria at Miss Universe. However, Simeonova did not meet the minimum age requirements of the pageant. Due to this, Nikoleta Todorova, a finalist at Miss Universe Bulgaria 2017, replaced Simeonova as Miss Universe Bulgaria 2017. Vian Sulaimani was supposed to represent Iraq at Miss Universe. However, Sulaimani was dethroned after it was discovered that she was married. Following Sulaimani's dethronement, the Miss Iraq Organization held a casting call to select the new representative of Iraq to Miss Universe. Sarah Idan emerged as the new Miss Iraq 2017. Pınar Tartan, Miss Turkey Supranational 2017, replaced Aslı Sümen as Miss Universe 2017 after Sümen replaced Itır Esen as Miss Turkey World 2017 hours after her crowning because of a tweet about the 2016 Turkish coup d'état attempt.
