The ICC World Test Championship, (WTC) , is a biennial world championship for Test cricket organised by the International Cricket Council (ICC). The winners of the tournament are awarded the Test Mace, which was previously held by the leader of the Test Championship. South Africa are the current champions, having defeated Australia in the 2025 final at Lord's.

WTC league games are organized by the host nation's cricket board, whereas the final is organized directly by the ICC. The inaugural ICC World Test Championship started with the 2019 Ashes series and finished with New Zealand lifting the trophy after defeating India in the final in June 2021. The second ICC World Test Championship started on 4 August 2021 with the England–India series and finished with Australia lifting the trophy after defeating India in the final in June 2023. The third ICC World Test Championship started on 16 June 2023 with the 2023 Ashes series and concluded with South Africa defeating Australia in the final.
