Porsgrunds Blad was a Norwegian newspaper, published in Porsgrunn in Telemark county first established on the 1 May 1846 as Ugeblad for Porsgrund og Omegn, initially apolitical, it became conservative-leaning, facing competition from the more clear-cut conservative newspaper, Grenmar. After a short time Porsgrunds Blad tried a liberal agenda, it went defunct in 1886 and was absorbed by Grenmar. Its last issue was printed on 31 March 1886.
