"Eternal Father, Strong to Save", is a hymn often associated with the Royal Navy or the United States Navy. Accordingly, it is often known as the Royal Navy Hymn or the United States Navy Hymn (or just The Navy Hymn), and sometimes by the last line of its first verse, For those in peril on the sea.

The original hymn was written by William Whiting of Winchester, England, in 1860. It was originally intended as a poem for a student of his, who was about to travel to the United States. In 1861, John B. Dykes, an Anglican clergyman, composed the tune "Melita" for this hymn. "Melita" is an archaic term for Malta, an ancient seafaring nation and the site of a shipwreck involving the Apostle Paul mentioned in Acts of the Apostles (chapters 27-28).

The first verse refers to God the Father's forbidding the waters to flood the earth as described in Psalm 104. The second verse refers to Jesus' miracles of stilling a storm and walking on the waters of the Sea of Galilee. The third verse references the Holy Spirit role in the creation of the earth in the Book of Genesis, while the final verse is a reference to Psalm 107.

The original words are:

Eternal Father, strong to save,
Whose arm hath bound the restless wave,
Who bidd'st the mighty ocean deep
Its own appointed limits keep;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

O Christ! Whose voice the waters heard
And hushed their raging at Thy word,
Who walkedst on the foaming deep,
And calm amidst its rage didst sleep;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

Most Holy Spirit! Who didst brood
Upon the chaos dark and rude,
And bid its angry tumult cease,
And give, for wild confusion, peace;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

O Trinity of love and power!
Our brethren shield in danger's hour;
From rock and tempest, fire and foe,
Protect them wheresoe'er they go;
Thus evermore shall rise to Thee
Glad hymns of praise from land and sea.
