Addalyn

Addalyn is a modern feminine name that emerged in the United States in the early 2000s. It appears to be a creative variant of Adeline or Madelyn, combining elements of popular names with the trendy '-lyn' suffix. The root 'Adal' comes from Germanic origins meaning 'noble' or 'nobility.' Addalyn gained modest popularity in the 2010s, particularly in the southern United States, as part of the trend toward elaborate versions of classic names. The name appeals to parents seeking something familiar yet distinctive. Though still relatively uncommon compared to similar names like Addison or Madelyn, Addalyn offers a sweet, feminine sound while maintaining the vintage charm of its root names, with a contemporary spelling that sets it apart.

Pronounced AD-uh-lin.

As of October 2026, Addalyn ranked #2194 in US births in 2025 SSA, peaked at #1026 in 2016.
