Etchū-Daimon Station (越中大門駅, Etchū-Daimon-eki) is a railway station on the Ainokaze Toyama Railway Line in the city of Imizu, Toyama Prefecture, Japan, operated by the third-sector railway operator Ainokaze Toyama Railway.

Etchū-Daimon Station is served by the Ainokaze Toyama Railway Line and is 26.5 kilometres from the starting point of the line at Kurikara.

It was privatized on 1 April 1984, becoming a station on JR West.

From 14 March 2015, with the opening of the Hokuriku Shinkansen extension from Nagano to Kanazawa, local passenger operations over sections of the Hokuriku Main Line running roughly parallel to the new shinkansen line were reassigned to different third-sector railway operating companies.
