Thih (鐵, hoà-ha̍k hû-hō: Fe, Latin-gí: ferrum), ia̍h thih-á, sī chiu-kî-pió lāi-té ê 1 chióng hoà-ha̍k goân-sò͘, goân-chú-hoan 26. Thih sī chióng kim-sio̍k, sio̍k tī tē 8 cho̍k goân-sò͘ (group 8 element), mā sī tē 4 chiu-kî goân-sò͘ (period 4 element). Thih sī chheⁿ-hu̍t goân-sò͘ ha̍p-sêng (stellar nucleosynthesis) siāng kài boé chò--chhut-lâi ê goân-sò͘, khiā kóng bián chhiau-sin-chheⁿ (supernova) ia̍h lūi-sū ê sū-kiāⁿ tō ū ê goân-sò͘ lāi-té siāng tāng--ê. Tō sī chit ê iân-kò͘, Thih sī ú-tiū--nih liōng siāng chē ê tāng kim-sio̍k (heavy metals).
