Mozaffari[3] (Persian: مظفری) was a steam yacht that was converted to a gunboat.

[1] Launched in 1899 as a Belgian merchant ship, it was purchased as a royal yacht for Mozaffar ad-Din Shah Qajar and served Persian navy from 1902 to 1914; and again between 1918 and 1936.

[2] Soon after it was launched, Adrien de Gerlache took over as her captain for an expedition to the Persian Gulf, seeking pearl.

[6] In April 1904, Mozaffari was used in an operation to hoist Persian flag at Abu Musa and Tunbs after removing those of Sharjah.

[3] An American diplomat reported in 1925 that Persepolis and Mozaffari were the two largest vessels of Iran.
