Bykowina (German: Friedrichsdorf) is a district in the south-east of Ruda Śląska, Silesian Voivodeship, southern Poland.

Since its beginnings it was closely tied with Kochłowice, originally formed on a hill within its borders.

After World War I in the Upper Silesia plebiscite 841 out of 1,198 voters in Bykowina (Friedrichsdorf) voted in favour of joining Poland, against 353 opting for staying in Germany.

It was then annexed by Nazi Germany at the beginning of World War II.

Bykowina constituted a gmina (municipality) that was merged into Nowy Bytom in 1951,[3] and as part of Nowy Bytom was amalgamated with Ruda to form Ruda Śląska on December 31, 1958.
