A Terceira Lâmina is the fourth solo album by Brazilian musician Zé Ramalho.

[1] As its two predecessors, the album mixes Northeast Brazil and rock influences.

[2] The opening track, "Canção Agalopada", features soprano Maria Lúcia Godoy and was based on a poem by Ramalho which was featured in his 1977 book Apocalipse (Apocalypse), and which uses the cordel forms martelo agalopado and galope à beira-mar.

[4][3] In a 2020 analysis for his blog at G1, Mauro Ferreira called the album "incisive", but compared it unfavorably to Ramalho's two previous efforts.

[5] The title track, according to Ramalho, "talks about the third child, my third phase - and the view of the third World War".
