Meitnerium ( pengucapan: /maɪtˈnɜriəm/ ) adalah unsur kimia dalam sistem periodik unsur yang memiliki lambang Mt dan nomor atom 109. Dinamai untuk mengenang fisikawan Austria, Lise Meitner , Mt adalah Unsur kimia sintetik dengan isotop yang paling stabil Mt-278 dengan waktu-paruh selama 8 detik.

Meitnerium pertamakali dibuat pada tahun 1982, di fasilitas riset nuklir Gesellschaft für Schwerionenforschung (GSI) di Jerman dengan cara membomardir target bismut dengan ion besi secara terus-menerus selama sepekan hingga akhirnya isotop 266 pertamakali terdeteksi. ^{[
