Leonard James Moorhouse (14 March 1904 – 4 May 1970) was a New Zealand swimmer who competed at the 1928 Summer Olympics.

[3] His father, Charles Edwin Moorhouse, was a keen yachtsman in Otago in his early years.

He received aquarobic therapy and spent so much time in the water that at age 18, he started competing in swimming.

Moorhouse was ranked third and thus did not qualify for financial assistance, but he chose to travel to the Amsterdam Olympics at his own expense.

[10] After the Olympic Games, he was highly critical of the training conditions in Amsterdam, where the American competitors were given preferential treatment and had access to the competition pool, whilst the New Zealand swimmers were given 10 minutes per day to train in a canal with stagnant water polluted with oil from ships.

[12] On 3 April 1937, Moorhouse married Kathleen Margaret "Peg" Blunden (born July 1917) at St Paul's Church in Christchurch.
