England men's captain Harry Kane will wear a OneLove armband for the team's Nations League games and at the 2022 World Cup in Qatar.
The Netherlands began the OneLove campaign prior to Euro 2020 to promote diversity and inclusion, and as a message against discrimination.
Belgium, Denmark, France, Germany, Norway, Sweden, Switzerland and Wales are also supporting the initiative.
Their captains will also wear the armband at the 2022 World Cup in Qatar.
Same-sex relationships and the promotion of same-sex relationships are criminalised in Qatar.
"I am honoured to join my fellow national team captains in supporting the important OneLove campaign," said Kane, who will wear the armband for the first time in a Nations League game against Italy on Friday.
