Who is the captain of Sri Lanka cricket?

As of my last knowledge update in September 2021, Dasun Shanaka is the captain of the Sri Lanka cricket team across all formats (Test, One Day International, and Twenty20 International).

However, there may have been changes to the captaincy since then. To obtain the most up-to-date information, I recommend checking the official websites or social media pages of the Sri Lanka Cricket Board (SLC).
