Ingeborg Birgersdotter, född omkring 1253, död 30 juni 1302, begravd i Mölln. Dotter till svenske riksföreståndaren jarl Birger Magnusson (död 1266) och prinsessan Ingeborg Eriksdotter av Sverige (död 1254).

Ingeborg Birgersdotter har felaktigt pekats ut som dotter till svenske kung Erik den läspe och halte (död 1250), vilken i själva verket var hennes morbror. Detta misstag beror sannolikt på att hon i samtida tyska källor betecknas som filiam regis Suecie och filia Regis Sweonum (se litteraturförteckningen nedan).
