Natal Day is a non-statutory holiday in Nova Scotia, Canada, celebrated on the first Monday in August. It coincides with other Civic Holidays across Canada.

Natal Day was originally celebrated on June 21, to commemorate the establishment of Halifax.

The tradition may have been created by the Nova Scotia Philanthropic Society who inaugurated an annual picnic in 1839 to celebrate the founding of Halifax.

Historical celebrations included; pig, sheep, and ox roasts, horse races, regattas, track and field event (hurdles, high jump, foot races etc.), greasy pig contests, and greasy pole contests among others. Public drunkenness was a frequent issue with reports on Natal Day of 1894 of civilians sneaking beer from the military canteen which ultimately led to a drunken brawl between civilians and soldiers. In 1876 reports from McNab's Island picnic reported "there was not much enjoyment there... for drunkenness and fighting prevailed generally, and there were many bruised faces and black eyes" and a new word 'jubilated' was coined to refer to the drunk and disorderly - with those completely unable to celebrate due to drunkenness being referred to as jubilous.

The first official Natal Day celebrations were held in August 1895 to mark the arrival of the new branch railroad line connecting to Dartmouth. While the rail construction was delayed, Dartmouth moved forward with a regatta and fireworks display.

In 1897, Natal Day celebrations corresponded with Queen Victoria's Diamond Jubilee. During the week long celebration which fell over June 21, the 'Jubilee' or 'Nymph' Fountain was unveiled in the Halifax Public Gardens by Ishbel, Marchioness of Aberdeen and Temair, the wife of John Campbell Gordon, 7th Earl of Aberdeen and Governor-General of Canada (1893-98).

The name Natal Day gained popularity in 1899 with the publication of Centenary Ode, by Halifax poet laureate John A. Bell on the 150th anniversary of the founding of Halifax.

Once more we greet thee, Natal Day,
The claim to greet thee ours alone;
With blithesome songs and banners gay,
The joy that stirs our hearts be shown.

An hundred years and fifty more
Thy morning light hath blest our eyes,
And still with ever-widening roar
Our voices to thy praises rise.

We hail thee as the dawning sun
Illumes the darkness with his ray,
And though his course be but begun
We know 'twill be a glorious day.

So, till a thousand years have rolled,
May every circling hour increase
The strength of ties that ne'er grow old,
The love of liberty and peace.
