‘Je me souviens’, meaning ‘I remember’ is the motto of Quebec. It may be paraphrased as conveying the meaning ‘We do not forget, and will never forget, our ancient lineage, traditions, and memories of all the past’.

Étienne-Paschal Taché is credited with having popularized the phrase. In 1883, his son Eugène-Étienne Taché, Assistant Commissioner for Crown lands in Quebec and architect of the provincial Parliament building, had the motto carved in stone below the coat of arms of Quebec which appears above the Parliament Building's main entrance door. The motto then came into official use, even though the coat of arms was not adopted until 1939.

‘Je me souviens’ is also the motto of the Royal 22nd Regiment, a Francophone regiment of the Canadian Forces.
