Józef Gosławski, also known as Iosif Vikentievich Goslavsky (Russian: Иосиф Викентьевич Гославский; 1865 – 30 January 1904) was a Polish architect mainly active in Baku, Azerbaijan.

In 1891, he graduated from the Institute of Civil Engineering in Saint Petersburg, and a year later he was appointed chief architect of the city of Baku (present-day capital of Azerbaijan).

His first task was to assist the local architect Robert Marfeld in designing and supervising the construction of the largest church in the Caucasus, the Alexander Nevsky Cathedral of Baku.

Gosławski's other architectural contributions in Baku were the Taghiyev Residence (present-day Azerbaijan State Museum of History), the Empress Alexandra Russian Muslim Boarding School for Girls (present-day Fuzuli Institute of Manuscripts of the National Academy of Sciences of Azerbaijan), a number of industrial buildings and houses.
