RESIN project
The RESIN project [1] gives the following definition:
A state of incomplete knowledge that can result from a lack of information or from disagreement about what is known or even knowable. [2]
Other International Definitions

Germany
Uncertainty can result from lack of information or from divergent opinions about what is or can be known. [3]
There may be many causes of uncertainty: faulty data, ambiguous concepts and terminology, or uncertainty about how people will behave. Uncertainty may be expressed in figures – for example where different climate models arrive at different forecasts about the rise in temperature. however, uncertainty may also be a qualitative statement by a team of experts.
Norway
Usikkerheten knyttet til analyseresultatene uttrykkes gjennom en vurdering av kunnskapsgrunnlaget de bygger på og resultatenes følsomhet for endringer i scenarioets forutsetninger og sentrale antagelser i analysene. [4]
Uncertainty related to the analysis results is expressed through an assessment of the knowledge base they are built upon, and the sensitivity of the results to changes in the prerequisites for the scenario and key assumptions in the analyses. [5]

United Kingdom (UK)
Uncertainty ia situation where the current state of knowledge is such that (1) the order or nature of things is unknown, (2) the consequences, extent, or magnitude of circumstances, conditions, or events is unpredictable, and (3) credible probabilities to possible outcomes cannot be assigned. [6]

Uncertainty is the degree to which a calculated, estimated, or observed value may deviate from the true value. [7]
