Níl aon tinteán mar do thinteán féin.

There's no hearth like your own hearth.

Note: This is almost certainly the most widely known of all the Irish proverbs. It has the same meaning as the English version: "There's no place like home"; although it is not considered trite. Perhaps it is best that there is no 'as Gaeilge' version of The Wizard of Oz. If you only learn one seanfhocal this week, this should be the one.
