The Invercargill March is a march composed by Alex Lithgow and named after his home town of Invercargill, in the South Island of New Zealand.
The Invercargill rates alongside John Philip Sousa's "Stars and Stripes Forever", Kenneth Alford's "Colonel Bogey March", and Johann Strauss' "Radetsky March" as one of the most popular in the world. It is especially popular in the United States, being a top favourite of the US Marines. It was the Regimental March of the 56th Infantry Regiment of the New York Guard during World War II.
In his book Invercargill - 150 Years Lloyd Esler's opening sentence reads "Invercargill was done a fine favour by Alex Lithgow who named his famous march after his boyhood home. The Invercargill March is possibly the best advertisement the town has ever had as the work is a brass-band favourite and the word 'Invercargill' is whispered amongst audiences worldwide. There is only one Invercargill in the world - this one."
