Sir Christopher Aylmer, 1st Baronet (c.1620-1671) was an Irish landowner.
The family was part of the Old English community of The Pale which largely remained Roman Catholic.
Following the Cromwellian conquest of Ireland his family had been deprived of their estates, but they recovered them following the Restoration and in 1662 Aylmer was made a baronet.
He was the father of the naval officers Matthew Aylmer, who became a distinguished Admiral, and George Aylmer who reached the rank of Captain before being killed at the Battle of Bantry Bay in 1689.
His eldest son Sir Gerald Aylmer, 2nd Baronet succeeded him in his baronetcy.
